From 3fa754c298b7e6fcbdbe615d6b609117fa7e0de9 Mon Sep 17 00:00:00 2001 From: Kukjin Kim Date: Thu, 22 Dec 2011 23:32:07 +0100 Subject: ARM: 7248/1: S5PV210: introduce arch/arm/mach-s5pv210/common.[ch] This patch introduces common.[ch] which are used only in the arch/arm/mach-s5pv210/ directory. The common.c file merges the cpu.c and init.c which are used commonly on S5PCV210/S5PC100 SoC and the common.h local header file replaces with plat/s5pv210.h file.
