Because of the module similarities of all am335x based phytec boards, we can

Instead of introducing new functions each time a new power supply

- has_battery - true when this board has a battery.
- use_battery_input - true when this board is supplied from the
battery input, but has a DC source instead of a real battery
- use_5v_input - true when this board can use the 5V input
The third one is introduced with this patch and allow to boot a board from 5v

The i.MX6 NAND update handler sets all bytes of OOB data to 0x00 in pages that
contain the FCB structure currently. So the first and second byte which is
used as the manufacturers bad block marker is in the 'bad block' state. A scan
for factory bad blocks will detect these blocks as bad while they are still ok.
The barebox issues a scan for factory bad blocks to rebuild the bad block table
if the NAND is brand new or the last four blocks of flash are erased.
To fix this problem set the first two bytes of OOB data to 0xFF explicitly.
There is a potential chance that the bbu handler will mark a real bad block as
factory good. That's not a problem for the ROM Loader, because the FCB is
protected by a checksum and the hamming_13_8 encoding. Additionally the current
implementation of the bbu handler does not check the bad block table or the
factory bad block marker before writing the FCB at the first page of the first
and second block.

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.

Now that we have printf support in the PBL we can use it right
after setup_c(). Add some debug messages to the early PBL code
to make it more clear what is happening there.

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 4b17d73c7d, 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
57b584d748 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)

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.
