I've had a look round but I cannot get a handle on fixing the issue.
I only have an i.mx31ads that failure doesn't occur, sorry I hope you
have more success than me.


For now I'll resubmit PATCH 1/2 with the changes to  board-mx31ads.h and
board-mx31ads.c but I'll not resubmit this patch to mx3_defconfig so
nobody will get it by default.

Does this seem OK to you ?
