Attempt to create a minimal EDK2 for some OMAP4430 devices

Status

Currently in early testing, just boots to early uefi

Building

Tested on Ubuntu 22.04.

First, clone EDK2.

cd ..
git clone https://github.com/tianocore/edk2.git -b edk2-stable202405--recursive
git clone https://github.com/tianocore/edk2-platforms.git

You should have all three directories side by side.

Next, install dependencies:

20.04 or later:

sudo apt install build-essential uuid-dev iasl git nasm python3-distutils crossbuild-essential-armel

Also see EDK2 website

Then ./scripts/firstrun.sh

Finally, you can use one of the device scripts in the scripts folder to build your bootimg/thing.

Then fastboot boot uefi.img from U-Boot console.
