Merge branch 'imx/multi-platform' of git://git.linaro.org/people/shaw…

…nguo/linux-2.6 into next/cleanup

From Shawn Guo:
"Here is the imx multi-platform support [1] that missed 3.7 merge window.
 Please pull it for 3.8 and exposing on linux-next.  As it touches a lot
 of files, I send it early, so that people can base their works off it
 to avoid conflicts."
