SMDKV310 board is based on Samsung S5PV310 SOC. This SOC is very much similar to S5PC210.

Signed-off-by: Chander Kashyap chander.kashyap@linaro.org Signed-off-by: Tushar Behera tushar.behera@linaro.org --- Changes for v2: - Coding Style Cleanup - Removed unwanted macros from board config file. - Ethernet controllor configuration is done using gpio structures. - MMC Controllor gpio configuration corrected. - Added MAINTAINERS entry. - Removed unwanted code from mem_setup.S. Changes for v3: - Comment style fixed - Added New macro in board config file. Changes for v4: - Fixed line with more than 80 characters in board config file

Added MMC SPL boot support for SMDKV310. This framework design is based on nand_spl support.

Signed-off-by: Chander Kashyap chander.kashyap@linaro.org --- Changes for v3: - spl file renamed to u-boot-mmc-spl.bin - spl directory renamed to mmc_spl - comments added in mkv310_image.c file Changes for v5: - Compilation warning mmc_boot.c: In function 'board_init_r': mmc_boot.c:51: warning: 'noreturn' function does return fixed.
