I asked Shawn about this and it seems that this patch is the way to go 
for the moment. So:

Acked-by: Dirk Behme <dirk.behme at gmail.com>

David: Artem: Building recent 3.6-rc1mainline with imx_v6_v7_defconfig 
is broken. We need this patch to get it working, again.

It would be nice if this patch could go as a fix into 3.6-rcX mainline 
asap. Could you help with this?

Many thanks and best regards

Dirk
