From 7d30e8b3815f804139271dfc31962ab74ce89650 Mon Sep 17 00:00:00 2001 From: Kukjin Kim Date: Mon, 14 Feb 2011 16:33:10 +0900 Subject: ARM: EXYNOS4: Add EXYNOS4 CPU initialization support This patch adds EXYNOS4 CPU support files in mach-exynos4, and basically they are moved from mach-s5pv310 so that it can support Samsung's new CPU name, EXYNOS4. The EXYNOS4 ingegrates a ARM Cortex A9 multi-core.
