Subject: ARM: tegra: clean up the common assembly macros into sleep.h
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=c2be5bfcc986e688c0c9b427b9fb33be178437d8;p=openwrt%2Fstaging%2Fblogic.git

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.
