This patch modifies the following. 1. Moves the SROM controller mapping from S5PV210 specific code to S5P common code. The SROM controller mapping can be used for all S5P SoCs. 2. Define the SROM controller physical address for S5P64X0, S5P6442, S5PC100, S5PV210 and S5PV310. Signed-off-by: Thomas Abraham <thomas.ab@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
