The above two lines should be added in omap-ocp2scp.txt (this file was
added as part of omap: add ocp2scp as a bus driver and is in
linux-next). However this file is still not in Felipe's xceiv branch.
So I'm not sure how I can get this patch merged in Felipe's tree
without conflict.

Thanks
Kishon
