grub: fix patch handling after AUTOTARGETS conversion

Closes #4093

AUTOTARGETS doesn't handle compressed patches, so the '400' patch did
not get applied.

Fix it by extracting the patch. With this, the '500' patch is no longer
needed.

+-
+-I   OVERVIEW
+-
+-    The 3c90X series ethernet cards are a group of high-performance busmaster
+-    DMA cards from 3Com.  This particular driver supports both the 3c90x and
+-    the 3c90xB revision cards.  3C90xC family support has been tested to some
+-    degree but not extensively.
+-
+-    Here's the licensing information:

+-    A PARTICULAR PURPOSE or MERCHANTABILITY.  Please read the associated
+-    documentation "3c90x.txt" before compiling and using this driver.
+-
+-
+-II  FLASH PROMS
+-
+-    The 3c90xB cards, according to the 3Com documentation, only accept the
+-    following flash memory chips:
+-
+-	Atmel AT29C512 (64 kilobyte)
+-	Atmel AT29C010 (128 kilobyte)
+-
+-    The 3c90x cards, according to the 3Com documentation, accept the
+-    following flash memory chips capacities:
+-
+-	64  kb (8 kB)
+-	128 kb (16 kB)
+-	256 kb (32 kB) and
+-	512 kb (64 kB)
+-
+-    Atmel AT29C512 (64 kilobyte) chips are specifically listed for both
+-    adapters, but flashing on the 3c905b cards would only be supported
+-    through the Atmel parts.  Any device, of the supported size, should
+-    be supported when programmed by a dedicated PROM programmer (e.g.
+-    not the card).
+-
+-    To use this driver in such a PROM, visit Atmel's web site and download
+-    their .PDF file containing a list of their distributors.  Contact the
+-    distributors for pricing information.  The prices are quite reasonable
+-    (about $3 US each for the 64 kB part), and are comparable to what one would
+-    expect for similarly sized standard EPROMs.  And, the flash chips are much
+-    easier to work with, as they don't need to be UV-erased to be reprogrammed.
+-    The 3C905B card actually provides a method to program the flash memory
+-    while it is resident on board the card itself; if someone would like to
+-    write a small DOS program to do the programming, I can provide the
+-    information about the registers and so forth.
+-
+-    A utility program, 3c90xutil, is provided with Etherboot in the 'contrib'
+-    directory that allows for the on-board flashing of the ROM while Linux
+-    is running.  The program has been successfully used under Linux, but I
+-    have heard problem reports of its use under FreeBSD.  Anyone willing to
+-    make it work under FreeBSD is more than welcome to do so!
+-
+-    You also have the option of using EPROM chips - the 3C905B-TX-NM has been
+-    successfully tested with 27C256 (32kB) and 27C512 (64kB) chips with a
+-    specified access time of 100ns and faster.
+-
+-
+-III GENERAL USE
+-
+-    Normally, the basic procedure for using this driver is as follows:
+-
+-	1.  Run the 3c90xcfg program on the driver diskette to enable the
+-	boot PROM and set it to 64k or 128k, as appropriate.
+-	2.  Build the appropriate 3c90x.fd0 or 3c90x.fd0 floppy image with
+-	possibly the value CFG_3C90X_XCVR defined to the transceiver type that
+-	you want to use (i.e., 10/100 rj45, AUI, coax, MII).
+-	3.  Run the floppy image on the PC to be network booted, to get
+-	it configured, and to verify that it will boot properly.
+-	4.  Build the 3c90x.rom or 3c90x.lzrom PROM image and program
+-	it into the flash or EPROM memory chip.
+-	5.  Put the PROM in the ethernet card, boot and enable 'boot from
+-	network first' in the system BIOS, save and reboot.
+-
+-    Here are some issues to be aware of:
+-
+-	1.  If you experience crashes or different behaviour when using the
+-	boot PROM, add the setting CFG_3C90X_BOOTROM_FIX and go through the
+-	steps 2-5 above.  This works around a bug in some 3c905B cards (see
+-	below), but has some side-effects which may not be desirable.
+-        Please note that you have to boot off a floppy (not PROM!) once for
+-        this fix to take effect.
+-	2.  The possible need to manually set the CFG_3C90X_XCVR value to
+-	configure the transceiver type.  Values are listed below.
+-	3.  The possible need to define CFG_3C90X_PRESERVE_XCVR for use in
+-	operating systems that don't intelligently determine the
+-	transceiver type.
+-
+-    Some things that are on the 'To-Do' list, perhaps for me, but perhaps
+-    for any other volunteers out there:
+-
+-	1.  Extend the driver to fully implement the auto-select
+-	algorithm if the card has multiple media ports.
+-	2.  Fix any bugs in the code <grin>....
+-	3.  Extend the driver to support the 3c905c revision cards
+-	"officially".  Right now, the support has been primarily empirical
+-	and not based on 3c905C documentation.
+-
+-    Now for the details....
+-
+-    This driver has been tested on roughly 300 systems.  The main two
+-    configuration issues to contend with are:
+-
+-	1.  Ensure that PCI Busmastering is enabled for the adapter (configured
+-	in the CMOS setup)
+-	2.  Some systems don't work properly with the adapter when plug and
+-	play OS is enabled; I always set it to "No" or "Disabled" -- this makes
+-	it easier and really doesn't adversely affect anything.
+-
+-    Roughly 95% of the systems worked when configured properly.  A few
+-    have issues with booting locally once the boot PROM has been installed
+-    (this number has been less than 2%).  Other configuration issues that
+-    to check:
+-
+-	1.  Newer BIOS's actually work correctly with the network boot order.
+-	Set the network adapter first.  Most older BIOS's automatically go to
+-	the network boot PROM first.
+-	2.  For systems where the adapter was already installed and is just
+-	having the PROM installed, try setting the "reset configuration data"
+-	to yes in the CMOS setup if the BIOS isn't seen at first.  If your BIOS
+-	doesn't have this option, remove the card, start the system, shut down,
+-	install the card and restart (or switch to a different PCI slot).
+-	3.  Make sure the CMOS security settings aren't preventing a boot.
+-
+-    The 3c905B cards have a significant 'bug' that relates to the flash prom:
+-    unless the card is set internally to the MII transceiver, it will only
+-    read the first 8k of the PROM image.  Don't ask why -- it seems really
+-    obscure, but it has to do with the way they mux'd the address lines
+-    from the PCI bus to the ROM.  Unfortunately, most of us are not using
+-    MII transceivers, and even the .lzrom image ends up being just a little
+-    bit larger than 8k.  Note that the workaround for this is disabled by
+-    default, because the Windows NT 4.0 driver does not like it (no packets
+-    are transmitted).
+-
+-    So, the solution that I've used is to internally set the card's nvram
+-    configuration to use MII when it boots.  The 3c905b driver does this
+-    automatically.  This way, the 16k prom image can be loaded into memory,
+-    and then the 3c905b driver can set the temporary configuration of the
+-    card to an appropriate value, either configurable by the user or chosen
+-    by the driver.
+-
+-    To enable the 3c905B bugfix, which is necessary for these cards when 
+-    booting from the Flash ROM, define -DCFG_3C90X_BOOTROM_FIX when building,
+-    create a floppy image and boot it once.
+-    Thereafter, the card should accept the larger prom image.
+-
+-    The driver should choose an appropriate transceiver on the card.  However,
+-    if it doesn't on your card or if you need to, for instance, set your
+-    card to 10mbps when connected to an unmanaged 10/100 hub, you can specify
+-    which transceiver you want to use.  To do this, build the 3c905b.fd0
+-    image with -DCFG_3C90X_XCVR=x, where 'x' is one of the following
+-    values:
+-
+-	0	10Base-T
+-	1	10mbps AUI
+-	3	10Base-2 (thinnet/coax)
+-	4	100Base-TX
+-	5	100Base-FX
+-	6	MII
+-	8	Auto-negotiation 10Base-T / 100Base-TX (usually the default)
+-	9	MII External MAC Mode
+-	255	Allow driver to choose an 'appropriate' media port.
+-
+-    Then proceed from step 2 in the above 'general use' instructions.  The
+-    .rom image can be built with CFG_3C90X_XCVR set to a value, but you
+-    normally don't want to do this, since it is easier to change the
+-    transceiver type by rebuilding a new floppy, changing the BIOS to floppy
+-    boot, booting, and then changing the BIOS back to network boot.  If
+-    CFG_3C90X_XCVR is not set in a particular build, it just uses the
+-    current configuration (either its 'best guess' or whatever the stored
+-    CFG_3C90X_XCVR value was from the last time it was set).
+-
+-    [[ Note for the more technically inclined:  The CFG_3C90X_XCVR value is
+-    programmed into a register in the card's NVRAM that was reserved for
+-    LanWorks PROM images to use.  When the driver boots, the card comes
+-    up in MII mode, and the driver checks the LanWorks register to find
+-    out if the user specified a transceiver type.  If it finds that
+-    information, it uses that, otherwise it picks a transceiver that the
+-    card has based on the 3c905b's MediaOptions register.  This driver isn't
+-    quite smart enough to always determine which media port is actually
+-    _connected_; maybe someone else would like to take on that task (it
+-    actually involves sending a self-directed packet and seeing if it
+-    comes back.  IF it does, that port is connected). ]]
+-
+-    Another issue to keep in mind is that it is possible that some OS'es
+-    might not be happy with the way I've handled the PROM-image hack with
+-    setting MII mode on bootup.  Linux 2.0.35 does not have this problem.
+-    Behavior of other systems may vary.  The 3com documentation specifically
+-    says that, at least with the card that I have, the device driver in the
+-    OS should auto-select the media port, so other drivers should work fine
+-    with this 'hack'.  However, if yours doesn't seem to, you can try defining
+-    CFG_3C90X_PRESERVE_XCVR when building to cause Etherboot to keep the
+-    working setting (that allowed the bootp/tftp process) across the eth_reset
+-    operation.
+-
+-
+-IV  FOR DEVELOPERS....
+-
+-    If you would like to fix/extend/etc. this driver, feel free to do so; just
+-    be sure you can test the modified version on the 3c905B-TX cards that the
+-    driver was originally designed for.  This section of this document gives
+-    some information that might be relevant to a programmer.
+-
+-    A.  Main Entry Point
+-
+-	a3c90x_probe is the main entry point for this driver.  It is referred
+-	to in an array in 'config.c'.
+-
+-    B.  Other Important Functions
+-
+-	The functions a3c90x_transmit, a3c90x_poll, a3c90x_reset, and
+-	a3c90x_disable are static functions that EtherBoot finds out about
+-	as a  result of a3c90x_probe setting entries in the nic structure
+-	for them.  The EtherBoot framework does not use interrupts.  It is
+-	polled.  All transmit and receive operations are initiated by the
+-	etherboot framework, not by an interrupt or by the driver.
+-
+-    C.  Internal Functions
+-
+-	The following functions are internal to the driver:
+-
+-	a3c90x_internal_IssueCommand - sends a command to the 3c905b card.
+-	a3c90x_internal_SetWindow - shifts between one of eight register
+-	windows onboard the 3c90x.  The bottom 16 bytes of the card's
+-	I/O space are multiplexed among 128 bytes, only 16 of which are
+-	visible at any one time.  This SetWindow function selects one of
+-	the eight sets.
+-	a3c90x_internal_ReadEeprom - reads a word (16 bits) from the
+-	card's onboard nvram.  This is NOT the BIOS boot rom.  This is
+-	where the card stores such things as its hardware address.
+-	a3c90x_internal_WriteEeprom - writes a word (16 bits) to the
+-	card's nvram, and recomputes the eeprom checksum.
+-	a3c90x_internal_WriteEepromWord - writes a word (16 bits) to the
+-	card's nvram.  Used by the above routine.
+-	a3c90x_internal_WriteEepromWord - writes a word (16 bits) to the
+-	card's nvram.  Used by the above routine.
+-
+-    D.  Globals
+-
+-	All global variables are inside a global structure named INF_3C90X.
+-	So, wherever you see that structure referenced, you know the variable
+-	is a global.  Just keeps things a little neater.
+-
+-    E.  Enumerations
+-
+-	There are quite a few enumerated type definitions for registers and
+-	so forth, many for registers that I didn't even touch in the driver.
+-	Register types start with 'reg', window numbers (for SetWindow)
+-	start with 'win', and commands (for IssueCommand) start with 'cmd'.
+-	Register offsets also include an indication in the name as to the
+-	size of the register (_b = byte, _w = word, _l = long), and which
+-	window the register is in, if it is windowed (0-7).
+-
+-    F.  Why the 'a3c90x' name?
+-
+-	I had to come up with a letter at the beginning of all of the
+-	identifiers, since 3com so conveniently had their name start with a
+-	number.  Another driver used 't' (for 'three'?); I chose 'a' for
+-	no reason at all.

+-Addendum by Jorge L. deLyra <delyra@latt.if.usp.br>, 22Nov2000 re
+-working around the 3C905 hardware bug mentioned above:
+-
+-Use this floppy to fix any 3COM model 3C905B PCI 10/100 Ethernet cards
+-that fail to load and run the boot program the first time around. If
+-they have a "Lucent" rather than a "Broadcom" chipset these cards have
+-a configuration bug that causes a hang when trying to load the boot
+-program from the PROM, if you try to use them right out of the box.
+-
+-The boot program in this floppy is the file named 3c905b-tpo100.rom
+-from Etherboot version 4.6.10, compiled with the bugfix parameter
+-
+-			CFG_3C90X_BOOTROM_FIX
+-
+-You have to take the chip off the card and boot the system once using
+-this floppy. Once loaded from the floppy, the boot program will access
+-the card and change some setting in it, correcting the problem. After
+-that you may use either this boot program or the normal one, compiled
+-without this bugfix parameter, to boot the machine from the PROM chip.
+-
+-[Any recent Etherboot version should do, not just 4.6.10 - Ed.]

+-
+-  Thu Dec 6 22:40:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>
+-
+-  * disabled all "advanced" features; this should make the code more reliable

+-  * reorganized the reset function
+-
+-  * always reset the address port, so that autoprobing will continue working
+-
+-  * some cosmetic changes
+-
+-  * 2.5
+-
+-  Thu Dec 5 21:00:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>
+-
+-  * tested the code against a CS8900 card
+-
+-  * lots of minor bug fixes and adjustments
+-
+-  * this is the first release, that actually works! it still requires some
+-    changes in order to be more tolerant to different environments
+-
+-  * 4
+-
+-  Fri Nov 22 23:00:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>
+-
+-  * read the manuals for the CS89x0 chipsets and took note of all the

+-
+-  Thu Nov 19 22:00:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>

+-
+-    The  driver has been tested on DE100, DE200 and DE202 cards  in  a

+-
+-    This  driver will NOT work   for the DE203,  DE204  and DE205 series  of

+-    chip.  See the 'ewrk3.c'   driver in the  Linux  source tree for running
+-    those cards.
+-
+-    I have benchmarked the driver with a  DE100 at 595kB/s to (542kB/s from)
+-    a DECstation 5000/200.

+-    
+-
+-    Peter Bauer's depca.c (V0.5) was referred to when debugging V0.1 of this
+-    driver.
+-
+-    The original DEPCA  card requires that the  ethernet ROM address counter
+-    be enabled to count and has an 8 bit NICSR.  The ROM counter enabling is
+-    only  done when a  0x08 is read as the  first address octet (to minimise
+-    the chances  of writing over some  other hardware's  I/O register).  The
+-    NICSR accesses   have been changed  to  byte accesses  for all the cards
+-    supported by this driver, since there is only one  useful bit in the MSB
+-    (remote boot timeout) and it  is not used.  Also, there  is a maximum of
+-    only 48kB network  RAM for this  card.  My thanks  to Torbjorn Lindh for
+-    help debugging all this (and holding my feet to  the fire until I got it
+-    right).
+-
+-    The DE200  series  boards have  on-board 64kB  RAM for  use  as a shared
+-    memory network  buffer. Only the DE100  cards make use  of a  2kB buffer
+-    mode which has not  been implemented in  this driver (only the 32kB  and
+-    64kB modes are supported [16kB/48kB for the original DEPCA]).
+-
+-    At the most only 2 DEPCA cards can  be supported on  the ISA bus because
+-    there is only provision  for two I/O base addresses  on each card (0x300
+-    and 0x200). The I/O address is detected by searching for a byte sequence
+-    in the Ethernet station address PROM at the expected I/O address for the
+-    Ethernet  PROM.   The shared memory  base   address  is 'autoprobed'  by
+-    looking  for the self  test PROM  and detecting the  card name.   When a
+-    second  DEPCA is  detected,  information  is   placed in the   base_addr
+-    variable of the  next device structure (which  is created if necessary),
+-    thus  enabling ethif_probe  initialization  for the device.  More than 2
+-    EISA cards can  be  supported, but  care will  be  needed assigning  the
+-    shared memory to ensure that each slot has the  correct IRQ, I/O address
+-    and shared memory address assigned.
+-
+-    ************************************************************************
+-
+-    NOTE: If you are using two  ISA DEPCAs, it is  important that you assign
+-    the base memory addresses correctly.   The  driver autoprobes I/O  0x300
+-    then 0x200.  The  base memory address for  the first device must be less
+-    than that of the second so that the auto probe will correctly assign the
+-    I/O and memory addresses on the same card.  I can't think of a way to do
+-    this unambiguously at the moment, since there is nothing on the cards to
+-    tie I/O and memory information together.
+-
+-    I am unable  to  test  2 cards   together for now,    so this  code   is
+-    unchecked. All reports, good or bad, are welcome.
+-
+-    ************************************************************************
+-
+-    The board IRQ   setting must be  at an  unused IRQ which  is auto-probed
+-    using Donald Becker's autoprobe routines. DEPCA and DE100 board IRQs are
+-    {2,3,4,5,7}, whereas the  DE200 is at {5,9,10,11,15}.  Note that IRQ2 is
+-    really IRQ9 in machines with 16 IRQ lines.
+-
+-    No 16MB memory  limitation should exist with this  driver as DMA is  not
+-    used and the common memory area is in low memory on the network card (my
+-    current system has 20MB and I've not had problems yet).
+-
+-    The ability to load this driver as a loadable module has been added. To
+-    utilise this ability, you have to do <8 things:
+-
+-    0) have a copy of the loadable modules code installed on your system.
+-    1) copy depca.c from the  /linux/drivers/net directory to your favourite
+-    temporary directory.
+-    2) if you wish, edit the  source code near  line 1530 to reflect the I/O
+-    address and IRQ you're using (see also 5).
+-    3) compile  depca.c, but include -DMODULE in  the command line to ensure
+-    that the correct bits are compiled (see end of source code).
+-    4) if you are wanting to add a new  card, goto 5. Otherwise, recompile a
+-    kernel with the depca configuration turned off and reboot.
+-    5) insmod depca.o [irq=7] [io=0x200] [mem=0xd0000] [adapter_name=DE100]
+-       [Alan Cox: Changed the code to allow command line irq/io assignments]
+-       [Dave Davies: Changed the code to allow command line mem/name
+-                                                                assignments]
+-    6) run the net startup bits for your eth?? interface manually 
+-    (usually /etc/rc.inet[12] at boot time). 
+-    7) enjoy!
+-
+-    Note that autoprobing is not allowed in loadable modules - the system is
+-    already up and running and you're messing with interrupts.
+-
+-    To unload a module, turn off the associated interface 
+-    'ifconfig eth?? down' then 'rmmod depca'.
+-
+-    To assign a base memory address for the shared memory  when running as a
+-    loadable module, see 5 above.  To include the adapter  name (if you have
+-    no PROM  but know the card name)  also see 5  above. Note that this last
+-    option  will not work  with kernel  built-in  depca's. 
+-
+-    The shared memory assignment for a loadable module  makes sense to avoid
+-    the 'memory autoprobe' picking the wrong shared memory  (for the case of
+-    2 depca's in a PC).
+-
+-    ************************************************************************
+-    Support for MCA EtherWORKS cards added 11-3-98.
+-    Verified to work with up to 2 DE212 cards in a system (although not
+-      fully stress-tested).  
+-
+-    Currently known bugs/limitations:
+-
+-    Note:  with the MCA stuff as a module, it trusts the MCA configuration,
+-           not the command line for IRQ and memory address.  You can
+-           specify them if you want, but it will throw your values out.
+-           You still have to pass the IO address it was configured as
+-           though.

+-/**************************************************************************
+-Etherboot -  BOOTP/TFTP Bootstrap Program
+-Intel EEPRO/10 NIC driver for Etherboot
+-Adapted from Linux eepro.c from kernel 2.2.17
+-
+-This board accepts a 32 pin EEPROM (29C256), however a test with a
+-27C010 shows that this EPROM also works in the socket, but it's not clear
+-how repeatably. The two top address pins appear to be held low, thus
+-the bottom 32kB of the 27C010 is visible in the CPU's address space.
+-To be sure you could put 4 copies of the code in the 27C010, then
+-it doesn't matter whether the extra lines are held low or high, just
+-hopefully not floating as CMOS chips don't like floating inputs.
+-
+-Be careful with seating the EPROM as the socket on my board actually
+-has 34 pins, the top row of 2 are not used.

+-		Details of the i82586.
+-
+-   You'll really need the databook to understand the details of this part,
+-   but the outline is that the i82586 has two separate processing units.
+-   Both are started from a list of three configuration tables, of which only
+-   the last, the System Control Block (SCB), is used after reset-time.  The SCB
+-   has the following fields:
+-		Status word
+-		Command word
+-		Tx/Command block addr.
+-		Rx block addr.
+-   The command word accepts the following controls for the Tx and Rx units:
+-  */

+-#define	RX_RESUME	0x0020
+-#define	RX_SUSPEND	0x0030
+-
+-/* The Rx unit uses a list of frame descriptors and a list of data buffer
+-   descriptors.  We use full-sized (1518 byte) data buffers, so there is
+-   a one-to-one pairing of frame descriptors to buffer descriptors.
+-
+-   The Tx ("command") unit executes a list of commands that look like:
+-	Status word	Written by the 82586 when the command is done.
+-	Command word	Command in lower 3 bits, post-command action in upper 3
+-	Link word	The address of the next command.
+-	Parameters	(as needed).

+-48K corresponding to window sizes of 64K, 48K, 32K and 16K respectively.
+-We can account for this be setting the 'SBC Base' entry in the ISCP table

+-value to all 24 bit physical addresses (in the SCP table and the TX and RX

+-  What follows in 'init_words[]' is the "program" that is downloaded to the

+-  reset address 0xfffff6.  This is designed to be similar to the EtherExpress,
+-  thus the unusual location of the SCB at 0x0008.
+-
+-  Even with the additional "don't care" values, doing it this way takes less
+-  program space than initializing the individual tables, and I feel it's much
+-  cleaner.
+-
+-  The databook is particularly useless for the first two structures, I had
+-  to use the Crynwr driver as an example.
+-
+-  The memory setup is as follows:
+-*/
+-
+-#define CONFIG_CMD	0x18
+-#define SET_SA_CMD	0x24
+-#define SA_OFFSET	0x2A
+-#define IDLELOOP	0x30
+-#define TDR_CMD		0x38
+-#define TDR_TIME	0x3C
+-#define DUMP_CMD	0x40
+-#define DIAG_CMD	0x48
+-#define SET_MC_CMD	0x4E
+-#define DUMP_DATA	0x56	/* A 170 byte buffer for dump and Set-MC into. */
+-
+-#define TX_BUF_START	0x0100
+-#define TX_BUF_SIZE	(1518+14+20+16) /* packet+header+TBD */
+-
+-#define RX_BUF_START	0x1000
+-#define RX_BUF_SIZE	(1518+14+18)	/* packet+header+RBD */
+-#define RX_BUF_END	(mem_end - mem_start - 20)
+-
+-/*
+-  That's it: only 86 bytes to set up the beast, including every extra
+-  command available.  The 170 byte buffer at DUMP_DATA is shared between the
+-  Dump command (called only by the diagnostic program) and the SetMulticastList
+-  command.
+-
+-  To complete the memory setup you only have to write the station address at
+-  SA_OFFSET and create the Tx & Rx buffer lists.
+-
+-  The Tx command chain and buffer list is setup as follows:
+-  A Tx command table, with the data buffer pointing to...
+-  A Tx data buffer descriptor.  The packet is in a single buffer, rather than
+-	chaining together several smaller buffers.
+-  A NoOp command, which initially points to itself,
+-  And the packet data.
+-
+-  A transmit is done by filling in the Tx command table and data buffer,
+-  re-writing the NoOp command, and finally changing the offset of the last
+-  command to point to the current Tx command.  When the Tx command is finished,
+-  it jumps to the NoOp, when it loops until the next Tx command changes the
+-  "link offset" in the NoOp.  This way the 82586 never has to go through the
+-  slow restart sequence.
+-
+-  The Rx buffer list is set up in the obvious ring structure.  We have enough
+-  memory (and low enough interrupt latency) that we can avoid the complicated
+-  Rx buffer linked lists by alway associating a full-size Rx data buffer with
+-  each Rx data frame.
+-
+-  I currently use one transmit buffer starting at TX_BUF_START (0x0100), and
+-  use the rest of memory, from RX_BUF_START to RX_BUF_END, for Rx buffers.

+-How I added the SIS900 card to Etherboot
+-
+-Author: Marty Connor (mdc@thinguin.org)
+-
+-Date:   25 Febrary 2001
+-
+-Description:
+-
+-This file is intended to help people who want to write an Etherboot
+-driver or port another driver to Etherboot.  It is a starting point.
+-Perhaps someday I may write a more detailed description of writing an
+-Etherboot driver. This text should help get people started, and
+-studying sis900.[ch] should help show the basic structure and
+-techniques involved in writing and Etherboot driver.
+-
+-***********************************************************************
+-
+-0. Back up all the files I need to modify:
+-
+-cd etherboot-4.7.20/src
+-cp Makefile Makefile.orig
+-cp config.c config.c.orig
+-cp pci.h pci.h.orig
+-cp NIC NIC.orig
+-cp cards.h cards.h.orig
+-
+-1. Edit src/Makefile to add SIS900FLAGS to defines
+-
+-SIS900FLAGS=	       	-DINCLUDE_SIS900
+-
+-2. edit src/pci.h to add PCI signatures for card

+- * Description    : Schneider & Koch G16 Ethernet Device Driver for

+- * Update History :
+- *
+--*/
+-
+-/*
+- * The Schneider & Koch (SK) G16 Network device driver is based
+- * on the 'ni6510' driver from Michael Hipp which can be found at
+- * ftp://sunsite.unc.edu/pub/Linux/system/Network/drivers/nidrivers.tar.gz
+- *
+- * Sources: 1) ni6510.c by M. Hipp
+- *          2) depca.c  by D.C. Davies
+- *          3) skeleton.c by D. Becker
+- *          4) Am7990 Local Area Network Controller for Ethernet (LANCE),
+- *             AMD, Pub. #05698, June 1989
+- *
+- * Many Thanks for helping me to get things working to:
+- *
+- *                 A. Cox (A.Cox@swansea.ac.uk)
+- *                 M. Hipp (mhipp@student.uni-tuebingen.de)
+- *                 R. Bolz (Schneider & Koch, Germany)
+- *
+- * See README.sk_g16 for details about limitations and bugs for the
+- * current version.
+- *
+- * To Do:
+- *        - Support of SK_G8 and other SK Network Cards.
+- *        - Autoset memory mapped RAM. Check for free memory and then
+- *          configure RAM correctly.
+- *        - SK_close should really set card in to initial state.
+- *        - Test if IRQ 3 is not switched off. Use autoirq() functionality.
+- *          (as in /drivers/net/skeleton.c)
+- *        - Implement Multicast addressing. At minimum something like
+- *          in depca.c.
+- *        - Redo the statistics part.
+- *        - Try to find out if the board is in 8 Bit or 16 Bit slot.
+- *          If in 8 Bit mode don't use IRQ 11.
+- *        - (Try to make it slightly faster.)

+- *
+- * The Network components are: dual ported RAM, Prom, I/O Reg, Status-,
+- * Controlregister and I/O Command.
+- *
+- * dual ported RAM: This is the only memory region which the LANCE chip
+- *      has access to. From the Lance it is addressed from 0x0000 to
+- *      0x3fbf. The host accesses it normally.
+- *
+- * PROM: The PROM obtains the ETHERNET-MAC-Address. It is realised as a
+- *       8-Bit PROM, this means only the 16 even addresses are used of the
+- *       32 Byte Address region. Access to a odd address results in invalid
+- *       data.
+- *
+- * LANCE I/O Reg: The I/O Reg is build of 4 single Registers, Low-Byte Write,
+- *       Hi-Byte Write, Low-Byte Read, Hi-Byte Read.
+- *       Transfer from or to the LANCE is always in 16Bit so Low and High
+- *       registers are always relevant.
+- *
+- *       The Data from the Readregister is not the data in the Writeregister!!
+- *
+- * Port: Status- and Controlregister.
+- *       Two different registers which share the same address, Status is
+- *       read-only, Control is write-only.
+- *
+- * I/O Command:
+- *       Any bitcombination written in here starts the transmission between
+- *       Host and LANCE.

++/* There are two ways to manage the TX descriptors on the tigon3.
++ * Either the descriptors are in host DMA'able memory, or they
++ * exist only in the cards on-chip SRAM.  All 16 send bds are under
++ * the same mode, they may not be configured individually.
++ *
++ * The mode we use is controlled by TG3_FLAG_HOST_TXDS in tp->tg3_flags.
++ *
++ * To use host memory TX descriptors:
++ *	1) Set GRC_MODE_HOST_SENDBDS in GRC_MODE register.
++ *	   Make sure GRC_MODE_4X_NIC_SEND_RINGS is clear.
++ *	2) Allocate DMA'able memory.
++ *	3) In NIC_SRAM_SEND_RCB (of desired index) of on-chip SRAM:
++ *	   a) Set TG3_BDINFO_HOST_ADDR to DMA address of memory
++ *	      obtained in step 2
++ *	   b) Set TG3_BDINFO_NIC_ADDR to NIC_SRAM_TX_BUFFER_DESC.
++ *	   c) Set len field of TG3_BDINFO_MAXLEN_FLAGS to number
++ *            of TX descriptors.  Leave flags field clear.
++ *	4) Access TX descriptors via host memory.  The chip
++ *	   will refetch into local SRAM as needed when producer
++ *	   index mailboxes are updated.
++ *
++ * To use on-chip TX descriptors:
++ *	1) Set GRC_MODE_4X_NIC_SEND_RINGS in GRC_MODE register.
++ *	   Make sure GRC_MODE_HOST_SENDBDS is clear.
++ *	2) In NIC_SRAM_SEND_RCB (of desired index) of on-chip SRAM:
++ *	   a) Set TG3_BDINFO_HOST_ADDR to zero.
++ *	   b) Set TG3_BDINFO_NIC_ADDR to NIC_SRAM_TX_BUFFER_DESC
++ *	   c) TG3_BDINFO_MAXLEN_FLAGS is don't care.
++ *	3) Access TX descriptors directly in on-chip SRAM
++ *	   using normal {read,write}l().  (and not using
++ *         pointer dereferencing of ioremap()'d memory like
++ *	   the broken Broadcom driver does)
++ *
++ * Note that BDINFO_FLAGS_DISABLED should be set in the flags field of
++ * TG3_BDINFO_MAXLEN_FLAGS of all unused SEND_RCB indices.

+- * Change History
+- *
+- *	Tigran Aivazian <tigran@sco.com>:	TLan_PciProbe() now uses
+- *						new PCI BIOS interface.
+- *	Alan Cox	<alan@redhat.com>:	Fixed the out of memory
+- *						handling.
+- *      
+- *	Torben Mathiasen <torben.mathiasen@compaq.com> New Maintainer!
+- *
+- *	v1.1 Dec 20, 1999    - Removed linux version checking
+- *			       Patch from Tigran Aivazian. 
+- *			     - v1.1 includes Alan's SMP updates.
+- *			     - We still have problems on SMP though,
+- *			       but I'm looking into that. 
+- *			
+- *	v1.2 Jan 02, 2000    - Hopefully fixed the SMP deadlock.
+- *			     - Removed dependency of HZ being 100.
+- *			     - We now allow higher priority timers to 
+- *			       overwrite timers like TLAN_TIMER_ACTIVITY
+- *			       Patch from John Cagle <john.cagle@compaq.com>.
+- *			     - Fixed a few compiler warnings.
+- *
+- *	v1.3 Feb 04, 2000    - Fixed the remaining HZ issues.
+- *			     - Removed call to pci_present(). 
+- *			     - Removed SA_INTERRUPT flag from irq handler.
+- *			     - Added __init and __initdata to reduce resisdent 
+- *			       code size.
+- *			     - Driver now uses module_init/module_exit.
+- *			     - Rewrote init_module and tlan_probe to
+- *			       share a lot more code. We now use tlan_probe
+- *			       with builtin and module driver.
+- *			     - Driver ported to new net API. 
+- *			     - tlan.txt has been reworked to reflect current 
+- *			       driver (almost)
+- *			     - Other minor stuff
+- *
+- *	v1.4 Feb 10, 2000    - Updated with more changes required after Dave's
+- *	                       network cleanup in 2.3.43pre7 (Tigran & myself)
+- *	                     - Minor stuff.
+- *
+- *	v1.5 March 22, 2000  - Fixed another timer bug that would hang the driver
+- *			       if no cable/link were present.
+- *			     - Cosmetic changes.
+- *			     - TODO: Port completely to new PCI/DMA API
+- *			     	     Auto-Neg fallback.
+- *
+- * 	v1.6 April 04, 2000  - Fixed driver support for kernel-parameters. Haven't
+- * 			       tested it though, as the kernel support is currently 
+- * 			       broken (2.3.99p4p3).
+- * 			     - Updated tlan.txt accordingly.
+- * 			     - Adjusted minimum/maximum frame length.
+- * 			     - There is now a TLAN website up at 
+- * 			       http://tlan.kernel.dk
+- *
+- * 	v1.7 April 07, 2000  - Started to implement custom ioctls. Driver now
+- * 			       reports PHY information when used with Donald
+- * 			       Beckers userspace MII diagnostics utility.
+- *
+- * 	v1.8 April 23, 2000  - Fixed support for forced speed/duplex settings.
+- * 			     - Added link information to Auto-Neg and forced
+- * 			       modes. When NIC operates with auto-neg the driver
+- * 			       will report Link speed & duplex modes as well as
+- * 			       link partner abilities. When forced link is used,
+- * 			       the driver will report status of the established
+- * 			       link.
+- * 			       Please read tlan.txt for additional information. 
+- * 			     - Removed call to check_region(), and used 
+- * 			       return value of request_region() instead.
+- *	
+- *	v1.8a May 28, 2000   - Minor updates.
+- *
+- *	v1.9 July 25, 2000   - Fixed a few remaining Full-Duplex issues.
+- *	                     - Updated with timer fixes from Andrew Morton.
+- *	                     - Fixed module race in TLan_Open.
+- *	                     - Added routine to monitor PHY status.
+- *	                     - Added activity led support for Proliant devices.
+- *
+- *	v1.10 Aug 30, 2000   - Added support for EISA based tlan controllers 
+- *			       like the Compaq NetFlex3/E. 
+- *			     - Rewrote tlan_probe to better handle multiple
+- *			       bus probes. Probing and device setup is now
+- *			       done through TLan_Probe and TLan_init_one. Actual
+- *			       hardware probe is done with kernel API and 
+- *			       TLan_EisaProbe.
+- *			     - Adjusted debug information for probing.
+- *			     - Fixed bug that would cause general debug information 
+- *			       to be printed after driver removal. 
+- *			     - Added transmit timeout handling.
+- *			     - Fixed OOM return values in tlan_probe. 
+- *			     - Fixed possible mem leak in tlan_exit 
+- *			       (now tlan_remove_one).
+- *			     - Fixed timer bug in TLan_phyMonitor.
+- *			     - This driver version is alpha quality, please
+- *			       send me any bug issues you may encounter.
+- *
+- *	v1.11 Aug 31, 2000   - Do not try to register irq 0 if no irq line was 
+- *			       set for EISA cards.
+- *			     - Added support for NetFlex3/E with nibble-rate
+- *			       10Base-T PHY. This is untestet as I haven't got
+- *			       one of these cards.
+- *			     - Fixed timer being added twice.
+- *			     - Disabled PhyMonitoring by default as this is
+- *			       work in progress. Define MONITOR to enable it.
+- *			     - Now we don't display link info with PHYs that
+- *			       doesn't support it (level1).
+- *			     - Incresed tx_timeout beacuse of auto-neg.
+- *			     - Adjusted timers for forced speeds.
+- *
+- *	v1.12 Oct 12, 2000   - Minor fixes (memleak, init, etc.)
+- *
+- * 	v1.13 Nov 28, 2000   - Stop flooding console with auto-neg issues
+- * 			       when link can't be established.
+- *			     - Added the bbuf option as a kernel parameter.
+- *			     - Fixed ioaddr probe bug.
+- *			     - Fixed stupid deadlock with MII interrupts.
+- *			     - Added support for speed/duplex selection with 
+- *			       multiple nics.
+- *			     - Added partly fix for TX Channel lockup with
+- *			       TLAN v1.0 silicon. This needs to be investigated
+- *			       further.
+- *
+- * 	v1.14 Dec 16, 2000   - Added support for servicing multiple frames per.
+- * 			       interrupt. Thanks goes to
+- * 			       Adam Keys <adam@ti.com>
+- * 			       Denis Beaudoin <dbeaudoin@ti.com>
+- * 			       for providing the patch.
+- * 			     - Fixed auto-neg output when using multiple
+- * 			       adapters.
+- * 			     - Converted to use new taskq interface.
+- *
+- * 	v1.14a Jan 6, 2001   - Minor adjustments (spinlocks, etc.)

+-	 *	This function handles timed functionality for the

+-	 *	-	Autonegotiation requires being allowed about
+-	 *		2 1/2 seconds before attempting to transmit a
+-	 *		packet.  It would be a very bad thing to hang
+-	 *		the kernel this long, so the driver doesn't
+-	 *		allow transmission 'til after this time, for
+-	 *		certain PHYs.  It would be much nicer if all
+-	 *		PHYs were interrupt-capable like the internal
+-	 *		PHY.
+-	 *	-	The ACT LED, which shows adapter activity, is
+-	 *		driven by the driver, and so must be left on
+-	 *		for a short period to power up the LED so it
+-	 *		can be seen.  This delay can be changed by
+-	 *		changing the TLAN_TIMER_ACT_DELAY in tlan.h,
+-	 *		if desired.  100 ms  produces a slightly
+-	 *		sluggish response.
++	 *	This function uses the TLAN's MII bus to retreive the contents

+-This software may be used and distributed according to the terms of
+-the GNU Public License, incorporated herein by reference.
+-
+-This is a tulip and clone driver for Etherboot.  See the revision
+-history in the tulip.c file for information on changes.  This version
+-of the driver incorporates changes from Bob Edwards and Paul Mackerras
+-who cantributed changes to support the TRENDnet TE100-PCIA NIC which
+-uses a genuine Intel 21143-PD chipset.  There are also various code
+-cleanups to make time-based activities more reliable.
+-
+-Of course you have to have all the usual Etherboot environment
+-(bootp/dhcp/NFS) set up, and you need a Linux kernel with v0.91g
+-(7.16.99) or later of the tulip.c driver compiled in to support some
+-MX98715 based cards.  That file is available at:
+-
+-  http://cesdis.gsfc.nasa.gov/linux/drivers/test/tulip.c
+-
+-NOTES
+-
+-I've tested this driver with a SOHOware Fast 10/100 Model SDA110A,
+-a Linksys LNE100TX v2.0, and a Netgear FA310TX card, and it worked at
+-both 10 and 100 mbits. Other cards based on the tulip family may work as
+-well.
+-
+-These cards are about 20$US, are supported by Linux and now Etherboot,
+-and being PCI, they auto-configure IRQ and IOADDR and auto-negotiate
+-10/100 half/full duplex. It seems like a pretty good value compared to
+-some of the pricier cards, and can lower the cost of building/adapting
+-thin client workstations substantially while giving a considerable
+-performance increase.
+-
+-On some PCI tulip clone chipsets (MX987x5, LC82C115, LC82C168) this driver 
+-lets the card choose the fastest speed it can negotiate with the peer
+-device.  On other cards, it chooses 10mbit half-duplex.
+-
+-I burned an AM27C256 (32KByte) EPROM with mx987x5.lzrom and it worked.
+-According to the data sheet the MX98715A supports up to 64K (27C512)
+-EPROMs, 
+-
+-I've liberally commented the code and header files in the hope that it
+-will help the next person who hacks the code or needs to support some
+-tulip clone card, or wishes to add functionality.
+-
+-Anyway, please test this if you can on your tulip based card, and let
+-me (mdc@thinguin.org) and the netboot list (netboot@baghira.han.de)
+-know how things go.  I also would appreciate code review by people who
+-program.  I'm a strong believer in "another set of eyes".
+-
+-Regards,
+-
