Ran the tests here, they seemed to pass:
http://www.pwsan.com/omap/testlogs/tmp-merge-2014-09-18/20140918132302/
However, I saw the following crash at boot on 37xxevm during one of
the boot test. Ran thirty more boot tests afterwards on that board
and it did not recur. It seems unlikely that the problem is related
to this series, but looks like we may have some intermittent boot
failure or race on 37xx :-(
