From: Naveen Krishna CH <chnav...@chnaveen.localdomain>
Memory subsystem of S5PC100 handles SROM, SRAM, OneDRAM, OneNand,
NAND Flash, DDRs.
mem.h is a common place for the register description of Memory subsystem
of S5PC100.
Note: Only SROM related registers are descibed now.

Changes since V1:
1. The header file is renamed to smc.h from mem.h
2. The Macros are renamed according to TRM.
Comments from Minkyu kang are fixed.
Note: Some of the defined macros are not used now. They are added to
facilitiate
simple cofiguration of SMC registers.
