When pressing the reset button on boot the system will enter the
recovery mode, this is done by setting a preboot command. Inside the
preboot command we will sleep and then check if the button is still
pressed, then tftp will be used to download the image and flash it. If
something fails after the DHCP state the network console will be
enabled.
LED0 is the "RF Active"/Yellow LED on the sysmobts-v2. We are not
using the 'yellow' LED alias as one needs to provide two functions
that call __led_set on led_yellow_on and led_yellow_off. Initialize
the GPIO direction in the board routine as the status_led code will
not be used.
The only ARM/kernel visible change is the change of the EEPROM. U-Boot
sadly does not support to select EEPROM with different page sizes and
address length. This is why we need to patch the common epprom code.
Introduce a new command to allow dynamic configuration of the EEPROM,
move the eeprom parameters into variables and change the code. This sadly
copies the SPI_X code as well. The address creation could be moved to
a different variable.
This code has been tested on RevC and RevD hardware and an IP address
could be obtained in both cases.
Add DVI output support and make it the default video output.
Currently the CLAA WVGA panel is supported, but this panel has to be purchased
separately, so using the DVI output as the default would allow more people to
try the splash screen feature on a mx51evk.
If someone still wants to use the CLAA WVGA, just set the panel variable as:
set panel claa

u-boot compilation fails for smdk5250 when we deselect CONFIG_LCD
from the main config file.
Following error was observed:
drivers/video/libvideo.o: In function `exynos_lcd_init':
/home/ajay/u-boot-samsung/drivers/video/exynos_fb.c:68: undefined reference to `lcd_set_flush_dcache'
This is because exynos video drivers have dependency on CONFIG_LCD.

Instead of using the serverip we get from the DHCP server, implicitly use
the broadcast address, which is automatically set when no ncip environment
variable is set. That way it isn't necessary to use a special DHCP
configuration to set the netconsole peer.

This saves stack and code memory for local copy, and
consumes initialized data memory. For 22 of the 29
kirkwood-based boards, this results in a global saving
of about 30 bytes. For 7 of them, it results in an
increase of 6 to 14 bytes.

This patch removes 2 small portions of board specific code that are
duplicated with common ARM code and thus unnecessary. These 2 portions
of code concern the mach id that is given by u-boot to the Linux kernel
to identify the system's MACH.
The first one was the possibility to change the MACH thanks to the
'mach_id' enviroment variable. This is possible thanks to the 'machid'
env variable (see arch/arm/lib/bootm.c:boot_jump_linux()).
The seconde one is the setting of the bi_arch_number. This is already
done in arch/arm/lib/board.c:board_init_f() since km_arm.h does #define
CONFIG_MACH_TYPE.

On kmcoge5un we faced some serious problems with the memory during
temperature tests. Reason was that we overwrite some registers for
memory settings which have to leave untouched. These where registers
0x20148 , 0x2014c and 0x20154.
So writing these registers is prohibited and this patch removes them
from all km related config files. Even if the problem was only
seen on kmcoge5un.

commit c73368150 (pmic: Extend PMIC framework to support multiple instances

The on-board number of available usdhc devices is something board
specific. The patch moves CONFIG_SYS_FSL_USDHC_NUM out of
mx6qsabre_common.h and adds usdhc2 and usdhc4 support for mx6qsabresd
board.
To keep the default mmc device for environment same as before (usdhc3),
it moves CONFIG_SYS_MMC_ENV_DEV out of mx6qsabre_common.h and changes
it to 1 for mx6qsabresd.

Support for a new command (defined at envs) - spl_export generates
the ATAGS image necessary for fast boot. Afterwards, it is stored
at ext4 partition.
Generated image format:
CRC [4B] SIZE [4B] PAYLOAD(ATAGS/DT) [SIZE]
Remarks:
- CRC is calculated only for PAYLOAD
- SIZE is the size of PAYLOAD
It is important to adjust ${splsize} when large image is generated.
It is defined as hex, since ext4 related commands expect it.
The ${spladdr} environment variable corresponds to
CONFIG_SYS_SPL_ARGS_ADDR
Additionally definitions for DFU have been refactored and support for
EFI has been added as well.

Calling the PMIC related functions at a later stage, ie, from board_late_init()
fixes the issue.
