Arnd pulled in tags/omap-for-v3.11/mailbox-signed, which is the branch
that should get merged to the mainline tree while we're waiting for
the generic mailbox framework from Jassi.

FYKI I, Suman and Loic have been co-ordinating offline. The generic
framework is almost there, Suman recently did the omap porting too,
Loic seems to be caught up with some other stuff. Lately we have been
joined by another developer LF.Tan to write the driver for a
not-yet-public IP.

cheers.
