lorbus at fedoraproject.org
lorbus at fedoraproject.org
Tue Mar 2 16:10:03 CET 2021
From: Christian Glombek <lorbus at fedoraproject.org>
The hardware is described in detail on Kobol's wiki at
https://wiki.kobol.io/helios64/intro/.
This commit is based on downstream work in Armbian by Aditya Prayoga [1].
The devicetree is taken from Linux and was originally submitted there by
Uwe Kleine-Koenig [2].
