* exynos: spl: Add a custom spi copy functionRajeshwari Shinde2013-12-032-4/+120
| | | | | | | | | | | | | | This patch implements a custom spi_copy funtion to copy u-boot from SF to RAM. This is faster then iROM spi_copy funtion as this runs spi at 50Mhz and also in WORD mode of operation. Changed a printf in pinmux.c to debug just to avoid the compilation error in SPL.

* EXYNOS: Move files from board/samsung to arch/armRajeshwari Shinde2013-07-0512-4/+3074
| | | | | | | | | | | | | | | | | | | | 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.
