So ports yosys and nextpnr updated (the last one built manually), openFPGALoader built (although cmake traditionally could not find library paths).
Firmware can only be flashed from root, but whatever.
So a fully open #fpga toolchain works under #DragonFlyBSD :)
The most important thing for me was to set the open collector mode for IO reliably. This is deadly important😜
I needed to make changes to two ports (cad/yosys and devel/nextpnr) to almost provide myself with tools. I can post a diff, but it is not combed and needs clarification.
