Tested on RPi3, probably works on 2, but 1 doesn't have enough power to run properly, but you could try (theoretically it should work).
This is Godot compiled for Raspberry Pi. As usual it didn't take any edits, just 3 hours of compile time. Compiled on actual RPi hardware (because I'm a scrub and can't get cross compiling to work)
The build binaries and install instructions!
