In commit abbab70 we added a prototype for hw_watchdog_init, in a
Freescale i.MX watchdog driver. We did not however guard it with an
__ASSEMBLY__ check and broke some platforms. Move this to the end of
the file with other prototypes and guard it.

Since commit de7d02aeb (mx6qsabresd: add usdhc2 and usdhc4 support)
SDHC3 device node is no longer 0, which breaks loading a uImage from SDHC3.
Fix it by adapting the default environment to use CONFIG_SYS_MMC_ENV_DEV as the
correct mmc node for loading the kernel from.
While at it, go back to using SDHC3 as the default mmc, since we have Yocto
images that generate an SD card containing U-boot,kernel and rootfs, so it is
more convenient to keep using SDHC3 as it was originally.

We enable console multiplexing and use both serial and LCD for stdout/stderr.
Initially, u-boot output console is observed via serial port.
If you also have a DP panel connected onto your SMDK5250 board,
you can switch to LCD console by typing "setenv stdout lcd".
You can always switch back to serial using "setenv stdout serial".
You can switch error console(stderr) as well, using similar commands.

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.

IGEP board PC16550D (ns16550) UART doesn't set the
Transmitter Empty (TEMT) Bit in SPL. This makes
U-Boot to hang while waiting for TEMT. Add the

avoid this issue.

When booting an IGEPv2 board from NAND with SPL, U-Boot hangs
trying to read the OMAP General Purpose Memory Controller (GPMC).
The reason is that the GPMC initialization function is called
inside spl_board_init() and this function is only executed when
CONFIG_SPL_BOARD_INIT is defined.

Some boards want to report more than just memory size. For example, it
might be useful to display the memory type (DDR2, DDR3) or manufacturer.
Add a weak function to support this requirement, accessed through a new
'meminfo' command.
Any example of the DRAM: output is below, just for illustration:
SMDK5250 # meminfo
DRAM: 2 GiB Elpida DDR3 @ 800MHz

Add support for SST 4KB sector granularity.
Many recent SST flashes, i.e. SST39VF3201B and similar of this family
are declared CFI-conformant from SST. They support CFI query, but implement
2 different sector sizes in the same memory: a 64KB sector (they call it
"block", std AMD erase cmd=0x30), and a 4KB sector (they call it "sector",
erase cmd=0x50). Also, CFI query on these chips, reading from address 0x2dh
of cfi query struct, detects a number of secotrs for the 4KB granularity
(flinfo shows it).
For all other aspects, they are CFI compliant, so, as Linux do, i think
it's a good idea to handle these chips in the CFI driver, with a fixup
to allow 4KB granularity, as should be expected, instead of 64KB.

Move all the C runtime setup code from every start.S
in arch/arm into arch/arm/lib/crt0.S. This covers
the code sequence from setting up the initial stack
to calling into board_init_r().
Also, rewrite the C runtime setup and make functions
board_init_*() and relocate_code() behave according to
normal C semantics (no jumping across the C stack any
more, etc).
Some SPL targets had to be touched because they use
start.S explicitly or for some reason; the relevant
maintainers and custodians are cc:ed.

In order to mx53 ROM to properly load the U-boot image, its header size should

,and this patch fixes it.
Also, even though the ROUND macro is already defined in common.h,
the reason for redefining it in image.h is explained by Stefano Babic:
"I will remark a previous comment - even if including common.h seems a
good idea to avoid duplications, it makes tools like mkimage to depend
on the selected board, because <board>_config must run. Even if this is
not a problem for us u-boot developers, it becomes an issue when these
tools are included in distros (like u-boot-tools in Ubuntu) and cannot
be packaged."

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.

FALCON MODE
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.

Since commit c733681 (pmic: Extend PMIC framework to support multiple instances

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