I just booted the latest master branch (b8fe178) with the hack below.
(Kernel command line: console=ttyO2,115200n8 root=/dev/mmcblk0p2 rw
rootfstype=ext3 rootwait)
Note that it is a ***HACK*** and should only be used temporarily.
Also note that I've been working on fixing up some of the am35x issues
including PM related ones that I'm in the middle of right now. If all goes
to plan, the am35x code will work better in the community in the
not-too-distant future.
