From 0bae6af6d704f026d4938739786e0a69d50177ca Mon Sep 17 00:00:00 2001 From: Lubomir Rintel Date: Tue, 5 May 2015 13:27:45 -0700 Subject: 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.
