I have one, I would like to use it as home router.
They have a repo with an image build script (u-boot 17.10 kernel 4.4 and ubuntu) here:
https://github.com/SolidRun/clearfog-gt-8k-buildThere is a fork that brings mainline to the board and it boots ok with arch.
However I had a bad pcie experience with an intel 7260 wlan card, which is not recognized. Seems like an armada-8k-pcie problem.
Apart from that, it's a nice hardware. Would love to see some support on it.
