From 830145796a5c8f1ca3f87ea619063c1d99a57df5 Mon Sep 17 00:00:00 2001 From: Kukjin Kim Date: Sun, 6 Nov 2011 13:54:56 +0900 Subject: ARM: EXYNOS: Add ARCH_EXYNOS and reorganize arch/arm/mach-exynos The arch/arm/mach-exynos4 directory (CONFIG_ARCH_EXYNOS4) has made for plaforms based on EXYNOS4 SoCs. But since upcoming Samsung's SoCs such as EXYNOS5 (ARM Cortex A15) can reuse most codes in current mach-exynos4, one mach-exynos directory will be used for them. This patch changes to CONFIG_ARCH_EXYNOS (arch/arm/mach-exynos) but keeps original CONFIG_ARCH_EXYNOS4 in mach-exynos/Kconfig to avoid changing in driver side.
