From dd4153d9af67496f6545831e72c743060d33a830 Mon Sep 17 00:00:00 2001 From: Kukjin Kim Date: Thu, 22 Dec 2011 23:31:28 +0100 Subject: [PATCH] ARM: 7247/1: S5PC100: introduce arch/arm/mach-s5pc100/common.[ch] 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.
