NixOS module and base SD card image for clockworkPi uConsole.
For now, only devices using RaspberryPi Compute Module 4 are supported.
Many things just doesn't work at the moment, the sd image boots, but it can only be confirmed using the HDMI output, and it's impossible to log in since the keyboard doesn't work.

Build one of the sd-image packages, e.g:
nix build .\#packages.aarch64-linux.\"sd-image-cm4-6.1-potatomania\" -L
Then flash the img file from result/sd-image. For more information see Development
section.
The kernels are available in 2 versions:
as normal aarch64-linux build, e.g:
nix build .\#packages.aarch64-linux.\"sd-image-cm4-6.1-potatomania\" -Land with a config where the kernel is cross built on x86_64-linux, e.g:
nix build .\#packages.aarch64-linux.\"sd-image-cm4-6.1-potatomania-cross-build\" -LFor cross building you'll need 2 machines: an x86_64-linux and an aarch64-linux build machine.
This is useful when you want to offload the kernel compilation to a potentially stronger computer
using cross compilation.
Once the image is flashed into an SD card the /boot/config.txt needs to be updated and copied over
from the relevant kernel's directory.
The available images, and NixOS modules are all discoverable using nix flake show.
