Linux with Wayland is now running on iPhone 7

Running postmarketOS on iPhone 7

Thanks to the developers of checkra1n and Corellium I was able to port PostmarketOS to the iPhone 7. Since I was only able to transfer small kernel images to the Phone, I only tested a very minimal PostmarketOS installation, but it is booting :) Image creation and flashing involves several steps.
