mailbox: Enable BCM2835 mailbox support
This mailbox driver provides a single mailbox channel to write 32-bit values to the VPU and get a 32-bit response. The Raspberry Pi firmware uses this mailbox channel to implement firmware calls, while Roku 2 (despite being derived from the same firmware tree) doesn't. The driver was originally submitted by Lubomir, based on the out-of-tree 2708 mailbox driver. Eric Anholt fixed it up for upstreaming, with the major functional change being that it now has no notion of multiple channels (since that is a firmware-dependent concept) and instead the raspberrypi-firmware driver will do that bit-twiddling in its own messages. [Jassi: made the 'mbox_chan_ops' struct as const and removed a redundant variable] Signed-off-by: Lubomir Rintel <lkundrak@v3.sk> Signed-off-by: Craig McGeachie <slapdau@yahoo.com.au> Signed-off-by: Eric Anholt <eric@anholt.net> Acked-by: Stephen Warren <swarren@wwwdotorg.org> Signed-off-by: Jassi Brar <jaswinder.singh@linaro.org>
