[fedora-arm] Raspberry Pi 5 support - how to contribute?

Hello, I've recently - and somewhat surprisingly - already got my hands into a Raspberry Pi 5. I would like to contribute to make it supported , as the Pi4 is. I have extensive Fedora experience, but not with ARM, and how the whole ecosystem works. What would be useful to get started with a test image for the Pi5? Or if that's not yet possible, what information or resources can be of use to get to that points? Thanks! Daniel M
