UEFI for the RaspberryPi 3B

[BjarneModeratorSuper Nova]

64-bit Tiano Core UEFI for the Raspberry Pi 3 (with devices, Linux, FreeBSD and Windows on Arm!)

Last updated Jul 8th, 2018.

This is a port of 64-bit Tiano Core UEFI firmware for the RPi3/RPi3B+ platforms, based on Ard Bisheuvel’s 64-bit and Microsoft’s 32-bit implementations.

Initially, this was supposed to be an easy walk in the park, where the Microsoft drivers just sorta slide into Ard’s UEFI implementation, and I call it a day. It turned out to be a bit more frustrating of an experience than that :-).

This is meant as a generally useful 64-bit UEFI implementation for the Pi3, good enough for most kinds of UEFI development and good enough for running real operating systems. It has been validated to install and boot Linux (SUSE, Ubuntu) and FreeBSD, and there is experimental Windows on Arm support as well.
