Memory subsystem of S5PC100 handles SROM, SRAM, OneDRAM, OneNand, NAND Flash, DDRs. smc.h is a common place for the register description of Memory subsystem of S5PC100. Note: Only SROM related registers are descibed now. Signed-off-by: Naveen Krishna Ch <ch.naveen@samsung.com> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>master
