This feature enables MagenBoy to run baremetal on RPI4 hardware

Todo:

  • Test if I can enable hard floats without using armv7a-none-eabihf target - Not possible according to my attempts and some guy on Discord
  • Fix the Mailbox with uncached memory not from the GPU
    • Add a non cached memory on the link script to use
  • Pin the stack in the link script (instead of an arbitrary location that the compiler can override)
  • Generate config.txt at build time to be able to sync it properly with all the params - Need to set core freq with the Mailbox instead (if possible)
  • Improve performance, currently running at 30 fps
    • Add support for DMA transfers
  • Add Joypad driver using the gpio
  • Clean the code before merging
  • Documentation
    • Document building for armv7a-none-eabihf since this is tier 3 target for rustc (including the nightly toolchain usage) if I have to use it
    • Document all the resources used for this project
    • Document running with Qemu
  • Arrange git (commits and reabse from master)

Only when #123 will be completed #109 will be closed
