From 31451afd2480caf3ae15da56cf9fc3cb3fb821cb Mon Sep 17 00:00:00 2001 From: Changhwan Youn Date: Tue, 4 Oct 2011 17:09:26 +0900 Subject: [PATCH] ARM: EXYNOS4: Add support SMDK4412 Board SMDK4412 board is same as a SMDK4212 board except that it has EXYNOS4412 SoC, thus it can share machine code with SMDK4212. This patch renames mach-smdk4212.c to mach-smdk4x12.c to support both SMDK4212 and SMDK4412 board with one machine file.
