From 3064f322783241f83b8e25b5acdd97a0d898a970 Mon Sep 17 00:00:00 2001 From: Tom Warren Date: Wed, 19 Sep 2012 14:08:52 -0700 Subject: Tegra20: Move some code files to common directories for upcoming Tegra30 patches. Move files that are going to be common between T20 and T30 into 'tegra-common' subdirs in AVP (arm720t), CPU (armv7), and shared (arch/arm/cpu/.) areas. Any files that are left behind in '/tegra20' will be copied to '/tegra30' subdirs and modified for that SoC. The 'common' files should need only minor changes. Include files (arch/arm/include/asm/arch-tegra/tegra20) will be done in a follow-on patch. Builds fine w/MAKEALL -s tegra20. Checkpatch.pl is clean.
