The Freescale MXS SoCs have a multi staged boot process which needs
different images composed out of different binaries. The ROM executes
a so called bootstream which contains multiple executables. The first
one is executed in SRAM and the purpose of this binary is to setup
the internal PMIC and the SDRAM. The second image is usually the
bootloader itself. In case of barebox the bootstream is composed
out of the self extracting barebox image (pblx) and the prepare
stage for setting up the SDRAM.
The bootstream image itself is useful for USB boot, but for booting from
SD cards or NAND a BCB header has to be prepended to the image. In case
of SD boot the image has the .mxssd file extension in barebox.
Since the bootstream images are encrypted they are not suitable for
2nd stage execution. For this purpose the 2nd stage images are generated.

U-Boot has code to replace the infamous Freescale bootlet code.
This patch adds this for barebox with some changes:
- Separate it more into mx23/mx28 functions instead of mxs functions
with #ifdefs for the actual SoC
- Add mx2x_power_init_battery_input() power entry point for boards
which have a regulated input on the battery pin to supply the board.

A lot of the arm build (especially PBL stuff) depends on section
garbage collection to be enabled. If it is disabled a lot of targets fail
to link properly. If module support is enabled garbage collection was
disabled on the premise that we throw away too many function which may be
needed in later modules.
The proper way to keep the functions around for use in modules, which
already works, is to annotate them with EXPORT_SYMBOL.
As module support is still marked as experimental I think it's reasonable
to expect users to make sure all symbols that are used by their modules
are properly annotated.

The phyCORE-AM335x is a SOM that can be connected to different
carrierboards like PCM-953, phyBOARD-WEGA and phyBOARD-MAIA.
It is enough for the bootloader to support the SOM specific
parts and can be so used also on different carrierboards.
Removed carrierboard specific settings like led and the
second ethernet slave.

We can't just enable SYS_SUPPORTS_LITTLE_ENDIAN for successful
little-endian qemu-malta barebox build. Some byte swapping-related
macros are missed, e.g.:
arch/mips/mach-malta/pci.c: In function 'pcibios_init':
arch/mips/mach-malta/pci.c:218:28: error: 'GT_PCI0_CMD_MBYTESWAP_BIT'
undeclared (first use in this function)

The AM3xxx can boot images containing a Configuration Header
(generated with omap_signGP) or images with GP Header (simple
size/address information in front of raw image). Update the
SPI NOR barebox update handler to detect the GP Header images.
These have 0x65726162 ('bare') at the offset header[10]. Also
automatically swap the endianess for non swapped images so
that the regular non swapped images can also be flashed.

We assumed that there is a special image format for SPI. This is not
the case. The AM33xx can boot either images generated with omap_signGP
or raw images which only have the image size and load address in front
of the image. Whether these images are booted from SPI or another
boot medium doesn't matter. The only special thing about SPI is that
the image is in big endian format.
- renames mk-am3xxx-spi-image.c to mk-omap-image.c as the image format
is not only supported by AM3xxx but also by the OMAP SoCs
- removes the option to specify the SoC
- introduces -s to build a big endian image
- detects if an image already is an image generated with omap_signGP
So the behaviour is like this:
raw image -> mk-omap-image -> prepend size/address -> image for SD/MMC
raw image -> mk-omap-image -s -> prepend size/address, big endian swap -> image for SPI
CH image -> mk-omap-image -> nothing, input == output
CH image -> mk-omap-image -s -> big endian swap -> image for SPI

The initialisation of the memory nodes on mvebu is a bit
compilcated:
pure_initcall(mvebu_memory_fixup_register)
of_register_fixup(mvebu_memory_of_fixup, NULL)
core_initcall(kirkwood_init_soc)
mvebu_set_memory()
core_initcall(of_arm_init)
of_fix_tree()
mvebu_memory_of_fixup()
First a mvebu common of_fixup function is registered, then the SoC
calls mvebu_set_memory which stores the memory base and size in global
variables. Afterwards the of_fixup is executed which fixes the memory
nodes according to the global variables.
Instead register a SoC specific fixup which directly calls mvebu_set_memory
with the memory base and size as arguments:
pure_initcall(kirkwood_register_soc_fixup);
of_register_fixup(kirkwood_init_soc, NULL);
core_initcall(of_arm_init)
of_fix_tree()
kirkwood_init_soc()
mvebu_set_memory(phys_base, phys_size);
