ARM: 7257/1: EXYNOS: introduce arch/arm/mach-exynos/common.[ch]
This patch introduces common.[ch] which are used only in the arch/arm/mach-exynos/ directory. The common.c file merges the cpu.c, init.c, irq-combiner.c and irq-eint.c files which are used commonly on EXYNOS SoCs and the common.h file replaces with plat/exynos4.h file. Cc: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
