From 150c24936b70ce36e11069038ba8e955704cab3a Mon Sep 17 00:00:00 2001 From: Tom Warren Date: Wed, 19 Sep 2012 15:50:56 -0700 Subject: Tegra20: Move some include files to arch-tegra for sharing with Tegra30 The move is pretty straight-forward. ap20.h and tegra20.h were renamed to ap.h and tegra.h. Some files remain in arch-tegra20 but 'include' a file in 'arch-tegra' with #defines & structs that will be common between T20 and T30 HW. HW-specific #defines, etc. stay in the 'arch-tegra20' 'root' file. All boards build OK w/MAKEALL -s tegra20. Checkpatch.pl runs clean. Seaboard works OK.
