Add weak functions to enable architecture depended preparation, address
advancing, cleaning up and error handling.
These weak functions provides the framwork to implemente arch/platform
dependent code for initializing/maintenance/restore the start address, size,
physical address as well as memory mapping before/between/after memory test.
arch_memory_failure_handle can also be implemented in case more care is needed
for arch/platform.

This patch removes some functionality from at91rm9200ek board but the
remaining functionality does now work with newer at91 code and
arm-relocation.
Currently missing features are:
- dataflash booting (due to missing HW for testing)
- MMC/SD-Card
- first stage bootloader support is completely removed (not needed for
NOR)
Cause this board was (some days ago) reference for all at91rm9200 based
boards this should be a good starting point to convert all remaining
at91rm9200 borads to at91 code. Aside from that this is a good base to
get some drivers between at91sam/at91rm/avr32 merged.

All arches except nios2 and microblaze call boot_get_fdt
from bootm_start in common/cmd_bootm.c.
Having nios2 and microblaze do so as well removes code from
their respective do_bootm_linux routines and allows removal of
a nasty ifdef from bootm_start.
In the case where boot_get_fdt returns an error bootm_start
returns and the platform specific do_bootm_linux routines
will never get called.
Also only check argv[3] for an fdt addr if argc > 3 first.
This is already the case for nios2.

boot_relocate_fdt is called on platforms with CONFIG_SYS_BOOTMAPSZ
defined to relocate the device tree blob to be inside the
boot map area between bootmap_base and bootmap_base+CONFIG_SYS_BOOTMAPSZ.
For the case where the blob needs to be relocated, space is
allocated inside the bootmap by calling lmb_alloc_base with
size passed in plus some padding:
of_len = *of_size + CONFIG_SYS_FDT_PAD;
For the case where the blob is already inside the bounds of the boot map
area, lmb_reserve is called to reserve the the space where the blob is
already residing. The calculation for this case is currently:
of_len = (CONFIG_SYS_BOOTMAPSZ + bootmap_base) - (ulong)fdt_blob;
This is wrong because it reserves all the space in the boot map area
from the blob to the end ignoring completely the actual size. The
worst case is where the blob is at the beginning and the entire boot map
area get reserved. Fix this by changing the length calculation to this:
of_len = *of_size + CONFIG_SYS_FDT_PAD;
This bug has likely never manifested itself because bootm has never
been called with the fdt blob already in the bootmap area. In my
testing on an OMAP3 beagle board I initially worked around the bug
by simply moving the initial location of the fdt blob. I have tested
with the new calculation with the fdt blob both inside and outside
the boot map area.

The change is currently needed to be able to remove the board
configuration scripting from the top level Makefile and replace it by
a simple, table driven script.
Moving this configuration setting into the "CONFIG_*" name space is
also desirable because it is needed if we ever should move forward to
a Kconfig driven configuration system.

When planning for more generalization and Makefile cleanup it became
obvious that the introduction of a separate CONFIG_MK_ name space for
config options that were set through scripting in the Makefile was
not a good idea.
Originally the idea was to provide a script-free approach to supply
configuration options - there was no real need for a separate name
space. But when we now convert the existing Makefile entries to make
use of this approach, it would mean that we have to touch a large
number of board config files and add #ifdef / #define sequences to
"convert" from the CONFIG_MK_ to the CONFIG_ name space.
It seems much cleaner to get rid of this somewhat arbitrary _MK
string now for the few boards that actually use it.

There are some boards where it's currently not possible to detect all
board information at runtime, therefore a new column was added to
boards.cfg .
This column can contain multiple options: a board configuration name,
optionally followed by a colon (':') and a list of options, which are
separated by comma (',').
In case of simple options like '256M_U_BOOT', these expand to
"#define CONFIG_MK_256M_U_BOOT 1" in config.h . In case of
assignments like 'RAM=8192', these expand to "#define CONFIG_MK_RAM
8192" in config.h .
Example:
FOO:HAS_BAR,BAZ=64
means:
- the name of the board config file is include/configs/FOO.h
- the generated file include/config.h will contain these
lines:
#define CONFIG_HAS_BAR 1
#define CONFIG_BAZ 64
