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.
