BCM2835 (used on Raspberry Pi) and BCM2836 (used on Raspberry Pi 2)
are similar enough.  One of the biggest differences is the ARM
processor.  It is reasonable to collect the source files into a
single place, arch/arm/mach-bcm283x/.

This SoC is used in the Raspberry Pi, for example.

Initial support is enough to boot to a serial console, execute a minimal
set of U-Boot commands, download data over a serial port, and boot a
Linux kernel. No storage or network drivers are implemented.
