On HREF+, SD card power supply is controlled by the Vaux3 regulator. In
order to enable the power supply, port the AB8500 PRCMU I2C read/write
code from Linux to U-Boot, and then write the appropriate registers via
those functions.

See ER 257608 Second core must not be woken up in U-Boot.
If the kernel boots with only one core (nosmp), it cannot be guaranteed that
the memory the second CPU is running from, is unused.

This patch is part of WP254081 which depends on WP252006.
Original patch from Rabin Vincent <rabin.vincent@stericsson.com>
The old text base, 0x05FC0000, is only 256KiB below the modem image,
which is loaded at 0x06000000 (96MiB).If the size of U-Boot image +
BSS is larger than 256KiB, the modem image will be overwritten.
Fix this by reducing the TEXT_BASE to 0x05600000 (86MiB). This allows
up to 10MiB for U-Boot + BSS, and also allows people to continue loading
fairly large initrds in the memory below U-Boot.

This patch is part of WP254081 which depends on WP252006.
* Fixed I2C, use real timeouts instead of counter
* Undefined CONFIG_BOOTTIME, since it as to be changed to new timer.c
* Merged V1 patches from Bangalore
The patches were merged manually, because of the differences
of the U-Boot baseline (Bangalore U-Boot 1.3.1, Lund 2009.11).
The original patches were created by Rabin Vincent
<rabin.vincent@stericsson.com>.

These are the patches for WP252006.
There will be a follow-up patched for WP254081.
Environment settings
* board_id bootargs parameter from board_id environment var
set in board_late_init().
* decreased bootdelay to 1 second
* added check for keypress on bootdelay==0
* removed preboot command and introduced "run cmdfile" instead
* changed rootfstype from ext2 to ext3
General I2C refactoring
* include/configs/u8500.h:
Enabled i2c command line commands.
Changed environment settings to use board_id as set in
board_late_init().
Added I2C address and configuration defines.
* board/st/u8500/Makefile: Replaced i2c.o with u8500_i2c.o.
* board/st/u8500/gpio.c, gpio.h: Added I2C busses to altfunc_table.
* board/st/u8500/init_mmc.c: removed config_extended_gpio() and therefore I2C
references. GPIOE settings are now in board_late_init().
* board/st/u8500/u8500.c:
Removed I2C/SD gpio settings from addr,value array.
board_late_init():
Determine and set board_id environment variable
0: mop500, 1: href500
Above boards have different GPIO expander chips which we can
distinguish by the chip id (1 and 3).
The board_id environment variable is needed for the Linux bootargs.

emmc.c, mmc.c, mmc_util.c: whitespace correction to pass diff --check
mmc_util.c: removed unused display_file_list(), fixed type warnings.

applied PACK3 changes:
* cpu/arm_cortexa9/start.S: reset register changed, but U-Boot reset
command still does not work.
* config.mk: build address changed to 0x05FC0000
* board/st/u8500/mmc.c: MBR change: descrease 4th partition size (userfs
2) from 0x00c0'0000 to 0x00b9'a000 sectors (6,442,450,944 to
6,228,541,440 bytes).
* board\st\u8500\init_mmc.c: modify bootargs to set board_id to HREF or
MOP. Is is an extremly ugly solution. It modifies the bootargs env
variable directly (bootargs[9] = board_id;), instead of setting a
additional environment variable board_id and use it in the bootargs
envvar.
* board/st/u8500/mmc.c: undocumented clock changes.
* board/st/u8500/mmc_utils.c:
new routine to switch to 4-bit interface.
The switch is done in mmc_read_file(). It would make more sense
to do so in mmc_init.
* board/st/u8500/u8500.c:
clock changes for HSI and I2C. I2C is now clocked by SOC1 PLL and runs
with 24 MHz (depends on boot ROM SOC1 initialisation)

clkinfo command shows current PLL and clock settings.
clkmaja changes certain clocks to be more U5500 (Maja) alike.
With make u8500_SRAM_config a U-Boot suitable to run from SRAM can be
compiled.

by the linux kernel and we still want to be able to use that timer for boottime measurement. IE leave the 3rd timer run until we're executing init. Added atags for u-boot timing measurements as communication with the kernel.

mmc init 0 will now initialise eMMC and mmc init 1 initialises MMC.
They can now be used in subsequent fatload or ext2load commands.
The numbering was choosing according to the Linux device numbering
/dev/mmcblk0 (eMMC) and /dev/mmcblk1 (MMC).

merged PACK2 changes: mmc and i2c frequency, put the second core into
wfe, default bootcmd.
