ARM: bcm2835: add mailbox driver
The BCM2835 SoC contains (at least) two CPUs; the VideoCore (a/k/a "GPU") and the ARM CPU. The ARM CPU is often thought of as the main CPU. However, the VideoCore actually controls the initial SoC boot, and hides much of the hardware behind a protocol. This protocol is transported using the SoC's mailbox hardware module. Here, we add a very simplistic driver for the mailbox module, and define a few structures for the property messages. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>
