I don't know if you are aware of it, but just to let you know, I've seen the
following patch that will interfere:
http://patchwork.ozlabs.org/patch/165311/
http://git.denx.de/?p=u-boot/u-boot-staging.git;a=commitdiff;h=72739219a12bf02820d29a89cb2b7fdc4d0e840f

You may want to merge it to your imx tree and rebase after it for your patch.

Right.
