The definition of "comma" exists in scripts/Kbuild.include.
We should not double it.
Note:
This was already fixed in Linux Kernel too.
See commit 226422d08c33 of Linux Kernel.

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.
- Export more functions to be more flexible when boards need non standard
setup.

Let's move it to the same place as well in barebox.

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.

This reverts commit 4b17d73c7da2, as it is incomplete and partially
broken. ARCH_IMX_EXTERNAL_BOOT_NAND does not depend on MTD, it just uses
some defines from the mtd/nand header, but does not actually depend on MTD
being compiled in.
For the other two cases there is a more complete fix merged with commit
57b584d748d4 that also enables the needed MTD write support.
Fixes:
(MACH_TX25 && MACH_PCA100 && MACH_PCM038) selects ARCH_IMX_EXTERNAL_BOOT_NAND
which has unmet direct dependencies (ARCH_IMX && MTD)

Currently, MIPS is the only architecture that needs
include/generated/asm-offsets.h, but we have got ./Kbuild file now.
It is a good reason to move asm-offsets.h rule from arch/mips/Makefile
to ./Kbuild and add dummy asm-offsets.c for the other architectures.
asm-offsets.h would be useful for all the architectures.
This commit does not implement include/generated/bounds.h,
but if necessary, it is easy to implement it.

Architecturally the cache contents are undefined so it might well
contain stale data at reset. So better be save than sorry.
I verifyed that the added instructions are defined for both, ARMv6 and
ARMv7, using the ARM Architecture Reference Manual, ARMv7-A and ARMv7-R
edition (ARM DDI 0406C.c). For the already existing mcr instruction see
the newly added comment.
This patch also unifies handling of ARMv6 and ARMv7, the isb instruction
can also be done on the latter via mcr which simplifies the code a bit.
