Minimal Raspberry Pi VPU firmware

This is a small firmware for RPi VPU (VideoCore4) versions 1/2/3 that is capable of initializing UART, VPU PLL (PLLC) and ARM itself. It's intended to be used instead of stock bootcode.bin on RPi's SD card. You need to have UART to see anything meaningful as far as output goes. The project additionally maintains a second-stage chainloader running on ARM capable of initializing eMMC, FAT, and the Linux kernel, as well as a shrinking set of patches to the Linux kernel.

This has been tested on RPi1 Model B (Hynix PoP DDR), RPi 2 Model B and RPi 3 Model B (both Elpida DDR), but it should work with minimal modifications on all of the models. Development primarily targets the RPi 2 Model B.

If you want to contact us because you're interested in contributing, development discussion occurs in #raspberrypi-internals on Freenode. Please come on IRC before randomly hacking on the codebase :-)
