We support a bunch of the AllWinner based a64 devices. Basically we need upstream support for the device in U-Boot (firmware) and the kernel (a device tree). Olimex are historically terrible and contributing anything to the upstream projects and as a result are generally considered as "community supported" devices which ends up being either someone does the work to get the required bits upstream or someone hacks together something that works enough for them and it never ends up being more widely supported. All the userspace pieces should work just fine, it should even be possible to get accelerated open graphics via the lima driver although I've not had time to test that on any of the Allwinner devices I have.

JFYI - since I last wrote here the Armbian project has provided more current images that currently work with the hardware. Images https://www.armbian.com/olimex-teres-a64/ worked and I am currently writing this message on the hardware (Olimex Teres Black) using Chromium ( 80.0.3987.149) on up-to-date Armbian Buster (10.3) - Linux teres-a64 5.4.28-sunxi64, Gnome 3.30.2 with Bulgarian translation (I contribute to the last one (-:) It is slow but it works! I hope upstreaming will continue and there will be support in Fedora for this eventually.
