Improvement: Add Arch Linux 64bit for RPI3 & 4

[df8oe]

There is a 64 bit port for RPI3 and 4 of Arch - I like it very much. It would be nice if you can add it in the future to the minimal distros : http://os.archlinuxarm.org/os/ArchLinuxARM-rpi-aarch64-latest.tar.gz

Sorry, I've tried. They have used UBoot for the 64-bit version, and I haven't been able to remove it as of yet. I'm not saying never, but it could be a long time before I can convert it.

Any progress?
