There is ARM SystemReady in a couple of flavours, one of which is UEFI: https://documentation-service.arm.com/static/68512137d12d1a1df64f239d https://documentation-service.arm.com/static/68512137d12d1a1... While I'm not exactly enthused about UEFI I prefer this to android's fork-the-kernel-tree-and-abandon model for your pocket-SBC. The last device I used with this booted fedora using arm UEFI no issue, several years ago. I don't see x86 going away for a long while if at all - too much software is built for it so the inertia is massive.
