+
+	  One well known example of this is PCMCIA- or PC-cards, credit-card
+	  size devices such as network cards, modems or hard drives which are
+	  plugged into slots found on all modern laptop computers.  Another
+	  example, used on modern desktops as well as laptops, is USB.
+
+	  Enable HOTPLUG and KMOD, and build a modular kernel.  Get agent
+	  software (at <http://linux-hotplug.sourceforge.net/>) and install it.
+	  Then your kernel will automatically call out to a user mode "policy
+	  agent" (/sbin/hotplug) to load modules and set up software needed

+ * SDA and SCL GPIOs have external pullups.  Setting the respective GPIO to 
+ * an input will make the signal a '1' via the pullup.  Setting them to 
+ * outputs will pull them down. 
+ *
+ * The GPIOs are open drain signals and are used as configuration strap inputs
+ * during power-up so there's generally a buffer on the board that needs to be 
+ * 'enabled' to drive the GPIOs.

+ * Modified for MIPS by Jun Sun, jsun@mvista.com
+ *
+ * . Simplify the interface between pci_auto and the rest: a single function.
+ * . Assign resources from low address to upper address.
+ * . change most int to u32.
+ *
+ * Further modified to include it as mips generic code, ppopov@mvista.com.
+ *
+ * 2001-10-26  Bradley D. LaRonde <brad@ltc.com>
+ * - Add a top_bus argument to the "early config" functions so that
+ *   they can set a fake parent bus pointer to convince the underlying
+ *   pci ops to use type 1 configuration for sub busses.
+ * - Set bridge base and limit registers correctly.
+ * - Align io and memory base properly before and after bridge setup.
+ * - Don't fall through to pci_setup_bars for bridge.
+ * - Reformat the debug output to look more like lspci's output.
+ *
+ * Cloned for SuperH by M. R. Brown, mrbrown@0xd6.org
+ *
+ * 2003-08-05  Paul Mundt <lethal@linux-sh.org>
+ * - Don't update the BAR values on systems that already have valid addresses
+ *   and don't want these updated for whatever reason, by way of a new config
+ *   option check. However, we still read in the old BAR values so that they
+ *   can still be reported through the debug output.

+    /* INSTRUCTION EMULATION
+    *  ---------------------
+    *
+    * Nios II processors generate exceptions for unimplemented instructions.
+    * The routines below emulate these instructions.  Depending on the
+    * processor core, the only instructions that might need to be emulated
+    * are div, divu, mul, muli, mulxss, mulxsu, and mulxuu.
+    *
+    * The emulations match the instructions, except for the following
+    * limitations:
+    *
+    * 1) The emulation routines do not emulate the use of the exception
+    *    temporary register (et) as a source operand because the exception
+    *    handler already has modified it.
+    *
+    * 2) The routines do not emulate the use of the stack pointer (sp) or the
+    *    exception return address register (ea) as a destination because
+    *    modifying these registers crashes the exception handler or the
+    *    interrupted routine.
+    *
+    * Detailed Design
+    * ---------------
+    *
+    * The emulation routines expect the contents of integer registers r0-r31
+    * to be on the stack at addresses sp, 4(sp), 8(sp), ... 124(sp).  The
+    * routines retrieve source operands from the stack and modify the
+    * destination register's value on the stack prior to the end of the
+    * exception handler.  Then all registers except the destination register
+    * are restored to their previous values.
+    *
+    * The instruction that causes the exception is found at address -4(ea).
+    * The instruction's OP and OPX fields identify the operation to be
+    * performed.
+    *
+    * One instruction, muli, is an I-type instruction that is identified by
+    * an OP field of 0x24.
+    *
+    * muli   AAAAA,BBBBB,IIIIIIIIIIIIIIII,-0x24-
+    *           27    22                6      0    <-- LSB of field
+    *
+    * The remaining emulated instructions are R-type and have an OP field
+    * of 0x3a.  Their OPX fields identify them.
+    *
+    * R-type AAAAA,BBBBB,CCCCC,XXXXXX,NNNNN,-0x3a-
+    *           27    22    17     11     6      0  <-- LSB of field
+    * 
+    * 
+    * Opcode Encoding.  muli is identified by its OP value.  Then OPX & 0x02
+    * is used to differentiate between the division opcodes and the remaining
+    * multiplication opcodes.
+    *
+    * Instruction   OP      OPX    OPX & 0x02
+    * -----------   ----    ----   ----------

+    * div           0x3a    0x25         0
+    * mul           0x3a    0x27      != 0

+    * one shifts the product left before adding in each of the partial products
+    * (a * mmmm) through (d * mmmm).
+    *
+    * To compute the upper half of a product (PPPP below), one adds in the
+    * partial products (d * mmmm) through (a * mmmm), each time following the
+    * add by a right shift of the product.
+    *
+    *     mmmm

+ * Semaphores are implemented using a two-way counter:
+ * The "count" variable is decremented for each process
+ * that tries to sleep, while the "waking" variable is
+ * incremented when the "up()" code goes to wake up waiting
+ * processes.
+ *
+ * Notably, the inline "up()" and "down()" functions can
+ * efficiently test if they need to do any extra work (up
+ * needs to do something only if count was negative before
+ * the increment operation.
+ *
+ * waking_non_zero() (from asm/semaphore.h) must execute
+ * atomically.
+ *
+ * When __up() is called, the count was negative before
+ * incrementing it, and we need to wake up somebody.
+ *
+ * This routine adds one to the count of processes that need to
+ * wake up and exit.  ALL waiting processes actually wake up but
+ * only the one that gets to the "waking" field first will gate
+ * through and acquire the semaphore.  The others will go back
+ * to sleep.
+ *
+ * Note that these functions are only called when there is
+ * contention on the lock, and as such all this is the
+ * "non-critical" part of the whole semaphore business. The
+ * critical part is the inline stuff in <asm/semaphore.h>
+ * where we want to avoid any extra jumps and calls.

+ * using "down()" cannot be killed until someone does an "up()" on

+/* Core file format: The core file is written in such a way that gdb
+   can understand it and provide useful information to the user (under
+   linux we use the 'trad-core' bfd).  There are quite a number of
+   obstacles to being able to view the contents of the floating point
+   registers, and until these are solved you will not be able to view the
+   contents of them.  Actually, you can read in the core file and look at
+   the contents of the user struct to find out what the floating point
+   registers contain.
+   The actual file contents are as follows:
+   UPAGE: 1 page consisting of a user struct that tells gdb what is present
+   in the file.  Directly after this is a copy of the task_struct, which
+   is currently not used by gdb, but it may come in useful at some point.
+   All of the registers are stored as part of the upage.  The upage should
+   always be only one page.
+   DATA: The data area is stored.  We use current->end_text to
+   current->brk to pick up all of the user variables, plus any memory
+   that may have been malloced.  No attempt is made to determine if a page
+   is demand-zero or if a page is totally unused, we just cover the entire
+   range.  All of the addresses are rounded in such a way that an integral
+   number of pages is written.
+   STACK: We need the stack information in order to get a meaningful
+   backtrace.  We need to write the data from (esp) to
+   current->start_stack, so we round each of these off in order to be able
+   to write an integer number of pages.
+   The minimum core file size is 3 pages, or 12288 bytes.
