This patch performs the following:

1) Convert the assembly code for memory and clock initialization to C code.
2) Move the memory and clock init codes from board/samsung to arch/arm
3) Creat a common lowlevel_init file across Exynos4 and Exynos5. Converted
   the common lowlevel_init from assembly to C-code
4) Made spl_boot.c and tzpc_init.c common for both exynos4 and exynos5.
5) Enable CONFIG_SKIP_LOWLEVEL_INIT as stack pointer initialisation is already
done in _main.
6) exynos-uboot-spl.lds made common across SMDKV310, Origen and SMDK5250.

TEST: Tested SD-MMC boot on SMDK5250 and Origen. 
      Tested USB and SPI boot on SMDK5250
      Compile tested for SMDKV310.

Congratulations on getting this patch together.

It looks correct, but I had some problems getting it to build.
Probably I am missing some other patch.

Configuring for smdk5250 board...

I will send a separate email about the patch situation. Here are the
patches I applied in reverse order - please let me know if I missed
any.

Hi Simon,

Thank you for reviewing the patch set.
You need to apply the following patches for it to compile and work fine.

EXYNOS: Add API for power reset and exit wakeup
EXYNOS: LDS file move to common
EXYNOS4210: Configure GPIO for uart
EXYNOS: Move files from board/samsung to arch/arm.

From the error it looks like "EXYNOS: Add API for power reset and exit
wakeup" patch is missing.

Regards,
Rajeshwari Shinde.

Hi Minkyu Kang,

I will have to rebase this patch on the latest u-boot-samsung tree,
before which please do let me know your comments on the same.

Rajeshwari Shinde
