Many thanks for these patches, with these I was able to run the latest
mainline kernel on boot to the console on my Orion O6 board. I think
others already tested just wanted to point out if you can keep me in
the loop, thanks.
If you feel is useful you can add:
Tested-by: Enric Balletbo i Serra <eballetb@redhat.com>
Thanks,
