I bisected a couple ARM boot failures in next-20141110 on atmel sama5 platforms down to
this patch, though I'm not quite yet sure how it's causing the failure.
I'm not getting any console output, so haven't been able to dig deeper
yet. Maybe the atmel maintainers (Cc'd) can help dig.

I've confirmed that reverting $SUBJECT patch (commit
b79055952badbd73710685643bab44104f2509ea2) on top of next-20141110 gets
things booting again.

Also, it only happens with sama5_defconfig, not with multi_v7_defconfig.
