From c2be5bfcc986e688c0c9b427b9fb33be178437d8 Mon Sep 17 00:00:00 2001 From: Joseph Lo Date: Thu, 16 Aug 2012 17:31:50 +0800 Subject: [PATCH] ARM: tegra: clean up the common assembly macros into sleep.h There are some common macros for Tegra low-level assembly code. Clean up them into one header file and move the definitions that will be re-used into it as well.
