When a ARCH_MVEBU platform is selected, generate barebox.kwb and
barebox.kwbuart images from barebox.bin, using kwbimage.
barebox.kwb is generated by executing kwbimage on the board
kwbimage.cfg file, and is therefore designed to be booted from the
default boot media of the board, as defined by kwbimage.cfg (typically
a NAND flash or SPI flash).
barebox.kwbuart is generated by executing kwbimage on the board
kwbimage.cfg file, but by overriding the boot media to be UART. This
image is suitable for usage with the kwbtool and is generally useful
for recovery purposes.

Squashed this fixup:
arm: ensure the build doesn't fail when kwbimage lacks the binary blob
mach-mvebu images for Armada 370 and Armada XP SoC require a DDR3
training code which should be extracted from existing bootable images
for the relevant board. When such binary blob has not been extracted,
the build of the .kwb and .kwbuart images will fail. This is annoying
as it makes the build of all Armada 370/XP defconfig fail, which can
be a problem for automated builds.
This proposal makes the failure of kwbimage not a fatal failure for
the build process, and shows a warning. The user therefore sees:
====================================================================
KWB barebox.kwb
Didn't find the file 'plathome-openblocks-ax3-binary.0' in '/home/thomas/projets/barebox' which is mandatory to generate the image
This file generally contains the DDR3 training code, and should be extracted from an existing bootable
image for your board. See 'kwbimage -x' to extract it from an existing image.
Could not create image
WARNING: Couldn't create KWB image due to previous errors.
KWBUART barebox.kwbuart
Didn't find the file 'plathome-openblocks-ax3-binary.0' in '/home/thomas/projets/barebox' which is mandatory to generate the image
This file generally contains the DDR3 training code, and should be extracted from an existing bootable
image for your board. See 'kwbimage -x' to extract it from an existing image.
Could not create image
WARNING Couldn't create KWB image due to previous errors.
====================================================================
The only drawback is that barebox-flash-image, which normally points
to barebox.kwb, becomes a stale symbolic link.

This syncs the localversion generation with the kernel.
At least one effect is that a barebox built from a tar archive no
longer marks itself as dirty. Also it moves some stuff from a scary
Makefile to a not-so-scary shell script.

Booting from SPI on an AM35xx (and possibly other TI SOCs) requires
a special format:
- 32 bit image size in big-endian
- 32 bit load address in big-endian
- binary image converted from little- to big-endian
The mk-am35xx-spi-image tool converts barebox.bin to
this format.

This is mostly useful during the initial port of barebox to a new
board which is supported by u-boot. It also allows starting barebox
from a SRAM-based u-boot SPL.
A different load address can be set like this:
make barebox.uimage UIMAGE_BASE=0x80000000
Also add barebox.ubl to CLEAN_FILES.

The dependencies for generating the environment do not work properly:
- If files are removed from the defaultenv, a subsequent make will not
update the default environment.
- If CONFIG_DEFAULT_ENVIRONMENT_PATH changes, the default environment
also will not be regenerated.
This patch fixes this by introducing a cmd_env which has the content of
$(ENV_FILES) in the command so that the if_changed mechanism recognizes
a change when $(ENV_FILE) changes. This also results in a nice " ENV "
string in the build process.

When building a special image from the original (compressed or
not) binary, to not overwrite KBUILD_BINARY.
This allows producing multiple images (such as MLO, UBL, ...)
from the (z)barebox.bin. In the case where no special image is
used, KBUILD_IMAGE is set to KBUILD_BINARY.
This patch was developed together with Sascha Hauer. Thanks!

Depending on the SoC a barebox.bin, barebox.netx, barebox.s5p, MLO image
is generated. With pbl support there now is an additional
arch/arm/pbl/zbarebox.bin image.
To help the user to determine which image should be flashed to his device,
generate a barebox-flash-image link.

This allows for creating a pre-bootloader binary for
- nand boot
- mmc boot
- compressed image
The pbl will be incharge of the lowlevel init if needed.
The barebox will skip it.
Import string functions from linux 3.4 (arch/arm/boot/compressed/string.c) and
implement a dummy panic.
For now on introduce dummy zbarebox* targets and c code that will contain later
the decompressor. This only implemeted on ARM.

If CONFIG_KALLSYMS is not set then barebox version is always "#0".
By-default on mips boards CONFIG_KALLSYMS don't set, so barebox
version does not increase after every build.
