during a recent RISE meeting, I conveyed the good news that Max and 9elements had released the SiFive unmatched port and it was upstreamed!
That was great. People seemed interested. Next request: Starfive visionfive2.
Now, we do have an oreboot port, so there is a code base to reference.
If somebody would like to look at getting this board ported, it would be a big help.
