[PATCH 05/12] ARM: S5PC100: introduce arch/arm/mach-s5pc100/common.[ch]
Kukjin Kim

Tue Dec 20 07:48:29 EST 2011
This patch introduces common.[ch] which are used only in the
arch/arm/mach-s5pc100/ directory. The common.c file merges
the cpu.c and init.c which are used commonly on S5PC100 SoC
and the common.h local header file replaces with plat/s5pc100.h
file.
