[U-Boot] [PATCH 4/4 V4] EXYNOS: Move files from board/samsung to arch/arm
Rajeshwari Shinde
rajeshwari.s at samsung.com
Thu Jul 4 08:59:17 CEST 2013
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.
Signed-off-by: Rajeshwari Shinde <rajeshwari.s at samsung.com>
---
Changes in V2:
- Rebased on latest u-boot-samsung tree.
- Incorporated review comments from Minkyu Kang.
Changes in V3:
- Optimised the mem_ctrl_init function for exynos4.
- Removed magic numbers.
Changes in V4:
- Used samsung_get_base api instead of hardcoding base address.
