Origen board is based upon S5PV310 SoC which is similiar to S5PC210 SoC.

Signed-off-by: Chander Kashyap chander.kashyap@linaro.org --- Changes for v2: - None Changes for v3: - Board entry added Alphabetically in boards.cfg - Used get_Ram_size function to calculate ram size Changes for v4: - CONFIG_MACH_TYPE defined to initialise MACH_TYPE in generic way - Used s5p_gpio_* functions for gpio operations
