From dc89ad1438cd8aa8b2cf508b5e839903fe1231a5 Mon Sep 17 00:00:00 2001 From: Tom Warren Date: Tue, 11 Dec 2012 13:34:12 +0000 Subject: Tegra30: Add arch-tegra30 include files Common Tegra files are in arch-tegra, shared between T20 and T30. Tegra30-specific headers are in arch-tegra30. Note that some of these will be filled in as more T30 support is added (drivers, WB/LP0 support, etc.). A couple of Tegra20 files were changed to support common headers in arch-tegra, also.
