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
