Subject: S5PC100: Memory SubSystem Header file, register description(SROMC).
X-Git-Tag: v2010.09-rc1~28^2~7^2~18^2~6
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=fe93100a64e045c14981b2d9129009b085d83f4b;p=u-boot

S5PC100: Memory SubSystem Header file, register description(SROMC).

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.
