I'm making an minikernel for my CM4 (testing in QEMU until it arrives), and i got the mmio, the gpio, the uart, the mailbox and the framebuffer to work, and all of that in rust, nice. Next step is an attempt to import LVGL in the kernel.

Heavily inspired by the rpi4-osdev repository, but i had to rewrite a lot to make it more rust like

Also, the mailbox thing was fun
