* ARM: rpi_b: enable SD controller, add related env/cmdsStephen Warren2013-03-20-0/+26
| | | | | | | | | | | Enable the SD controller driver for the Raspberry Pi. Enable a number of useful MMC, partition, and filesystem-related commands. Set up the environment to provide standard locations for loading a kernel, DTB, etc. Provide a boot command that loads and executes boot.scr.uimg from the SD card; this is written considering future extensibilty to USB storage.

* ARM: bcm2835: add mailbox driverStephen Warren2013-03-20-0/+407
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>
