With the VC reader blocked and the ARM writing, MAIL0_STA reads empty
permanently while MAIL1_STA goes from empty (0x40000000) to non-empty
(0x00000001-0x00000007) to full (0x80000008).This bug ended up having no effect on us, because all of our
transactions in the client driver were synchronous and under a mutex.Suggested-by: Phil Elwell

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.
