The "mtest" command is of little practical use (if any), and
experience has shown that a large number of board configurations
define useless or even dangerous start and end addresses. If not even
the board maintainers are able to figure out which memory range can be
reliably tested, how can we expect such from the end users? As this
problem comes up repeatedly, we rather do not enable this command by
default, so only people who know what they are doing will be
confronted with it.
As this changes the user interface, we allow for a grace period
before this change takes effect. For now, we make "mtest"
configurable through the CONFIG_CMD_MEMTEST variable, which is defined
in include/config_cmd_default.h; we also add an entry to
doc/feature-removal-schedule.txt which announces the removal of this
default setting in two releases from now, i. e. with v2013.07.

Currently each mpc512x board has its own LAW and CS config code,
we should avoid this code duplication. Allow all boards to use
common code by only defining LAW and CS config macros like
CONFIG_SYS_CSx_START, CONFIG_SYS_CSx_SIZE and CONFIG_SYS_CSx_CFG.
Also allow common configuration of additional CS parameters by
CONFIG_SYS_CS_ALETIMING, CONFIG_SYS_CS_BURST, CONFIG_SYS_CS_DEADCYCLE
and CONFIG_SYS_CS_HOLDCYCLE options.

This patch adds a custom U-Boot command "wdogtoggle" which enables the
external hardware watchdog toggling via an GPIO pin on the a4m2k
board. After issuing this commands, the watchdog will be serviced
by U-Boot so that the user can use all U-Boot commands from the
prompt.

This patch adds the a4m2k MPC5200B board port. Its a derivate of
the a3m071 board with only minor changes.
Additionally this patch includes some clean-up changes:
- Remove I2C support from a3m071 as its unused
- Fix/enhance default env variables
- Fix some comments
- Add newly introduced CONFIG_SPL_TARGET to automatically build
"u-boot-img.bin"
- Fix dtb patching in READ desciption for SPL Linux booting:
"fdt chosen" needs to get called to patch/create the chosen node.
- Add missing call to spl_board_init():
Define CONFIG_SPL_BOARD_INIT so that spl_board_init() will get
called in the SPL version.

On MPC5200, the initial RAM (and gd) is located in the internal
SRAM. So we can actually call the preloader console init code
before calling initdram(). This makes serial output (printf)
available very early, even before SDRAM init, which has been
an U-Boot priciple from day 1.

This does not actually change normal behaviour, but adds a check that
should detect corruption of relocation data (e.g. by using BSS data
prior to relocation).
Also add additional debugging output when enabled.
During this investigation, two situations have been seen:
1. calculate_relocation_address():
uintptr_t size = (uintptr_t)&__bss_end - (uintptr_t)&__text_start;
turns into
111166f: b8 83 c4 17 01 mov $0x117c483,%eax
whih is beyond the end of bss:
0117b484 g .bss 00000000 __bss_end
Somehow the __bss_end here is 255 bytes ahead.
2. do_elf_reloc_fixups():
uintptr_t size = (uintptr_t)&__bss_end - (uintptr_t)&__text_start;
Here the __text_start is 0 in the file:
1111d9f: bb a0 e0 13 01 mov $0x113e0a0,%ebx
1111da4: 81 ef 00 00 00 00 sub $0x0,%edi
As it happens, both of these are in pre-relocation code.
For these reasons we silent check and ignore bad relocations.

The memory layout calculations are done in calculate_relocation_address(),
and coreboot has its own version of this function. But in fact all we
really need is to set the top of usable RAM, and then the base version
will work as is.
So instead of allowing the whole calculate_relocation_address() function
to be replaced, create board_get_usable_ram_top() which can be used by
a board to specify the top of the area where U-Boot relocations to.

UBI can mount volumes by name or number The current code forces you
to name the volume by prepending every name with "ubi:".
>From fs/ubifs/super.c
* There are several ways to specify UBI volumes when mounting UBIFS:
* o ubiX_Y - UBI device number X, volume Y;
* o ubiY - UBI device number 0, volume Y;
* o ubiX:NAME - mount UBI device X, volume with name NAME;
* o ubi:NAME - mount UBI device 0, volume with name NAME.
Now any name passed in any of the above forms are allowed.
Also update the configs that referenced ubifsmount.
