Could you update this patch to align with the discussion we had the last time this was posted in December? e.g., http://www.spinics.net/lists/arm-kernel/msg388002.html You can ignore the problems with the VAR-SOM-OM that were discussed; those were indeed due to an old DT file in use, as Suman suspected.
