Four methods for the creation of device files in /dev are now
proposed:
- static method uses device table as before
- devtmpfs method enables this feature in kernel
- mdev method adds mdev starting script to the file system
and selects mdev itself for installation
- udev method selects udev for installation
All dynamic methods are based on devtmpfs, so one doesn't need to care
about /dev folder.

This is useful for ARCHes like PowerPC that have a whole lot of
special targets for each different board. The kernel image target
tells make which OpenFirmware machine description file is combined into
the kernel binary.

As per the discussion at
http://lists.busybox.net/pipermail/buildroot/2010-December/040030.html,
remove the bits that forced the IPv6 configuration in the kernel
depending on the toolchain ability to support (or not) IPv6. You may
have a toolchain with IPv6 support but still don't want to have IPv6
in your kernel.
The only parameters we adjust in the kernel configuration are:
* ARM EABI, since we got a lot of bug reports regarding misconfigured
kernel compared to the ABI used by userspace applications.
* initramfs, since its contents are generated by Buildroot itself

linux-% shortcut targets (short for linux26-%) ignores the ouput dir
$(O) so that 'make O=output.arm linux-menuconfig' is actually run in the
default $(O) directory output/ and not in output.arm/. Fix by passing on
$(O) if set.

Both i386 and x86_64 architectures are supported by the arch/x86
directory in the kernel. So, when we copy the kernel configuration
file to arch/$(KERNEL_ARCH)/configs/, it does not work because
arch/i386 and arch/x86_64 do not exist.
So, we introduce KERNEL_ARCH_PATH, which is the path to the
architecture specific directory in the kernel source tree.

The kernel being a component that often needs a fairly important set
of changes to be adapted to a particular hardware platform, having
maximum flexibility on the patching process is a nice
thing. Therefore, as per the discussions from the Buildroot Developer
Day, we add a mechanism to apply a list of patches (that could come
either from URLs, local files or local directories).

Now that minimal kernel defconfigs are used in Buildroot, the problem
is that copying those minimal configuration files to .config in the
kernel source tree does not work, as kconfig will ask interactively
what should be the value for all unspecified options.
On suggestion on Sam Ravnborg, the easiest way to solve this is to
import the minimal defconfig file as a defconfig inside the kernel
tree (in arch/$(ARCH)/configs) and configure the kernel with it.

The linux.mk rewrite lost the DEPMOD setting while installing modules
which means depending on host-module-init-tools has been useless.
Instead, the build system has been executing /sbin/depmod.
While we're here, drop the INSTALL_MOD_PATH since LINUX26_MAKE_FLAGS
already contains it.

Building with linux-2.6.36 and initramfs support causes the build to
pause while it prompts for newer options (uid/gid/compression). So
have the build system inject the newer options into the linux config
automatically. Older versions should just ignore these.

The current linux code overrides LDFLAGS that the kernel itself might be
setting up. Looking at the history, there doesn't seem to be any reason
for this override. It was added in ea8b1fa6a60705 without any logic.

Linux has been using "usr/initramfs_data.cpio" for a few releases as the

And all the infrastructure surrounding it. A broken sed implementation
is quite rare nowadays, as seen by the fact that the current host-sed

When initramfs was not selected as a root filesystem, we forcefully
disabled the initramfs in the kernel configuration.
However, it prevents an user from manually managing its initramfs, as
we override the option he has set in his kernel configuration
file. There's no real reason to do so: when initramfs is not selected
as the root filesystem, just don't touch initramfs related options in
the kernel configuration.

Just as we do for U-Boot, error out in the Linux kernel makefile when
the defconfig name or the configuration file path are not
correct. What prompted me to implement this was a report on IRC from
an user using BR 2010.05 and not understand why the kernel build
process was failing. It was because he just forgot to set the path of
the configuration file.
Of course, it doesn't catch all mistakes (like pointing to a
non-existing defconfig or to a non-existing configuration file), but
it at least catches basic mistakes.
