Is there any other issue that needs to be addressed before creating wip/quicklogic branch and regenerating Yosys master+wip branch?

I think the broader issue is how to maintain long term maintenance of this wip/ branch. One of the recent pushes has been to eliminate wip/ branches, either by getting the patches merged upstream, or in the case of yosys, making plugins rather than modifying yosys directly. Ideally this would go into upstream yosys, but I understand that might be hard to impossible.

If getting into upstream yosys is not going to happen, then I believe converting this PR into a plugin, likely under its own project, is my preferred path forward.

Ok, I will create a PR which will add those changes as a separate Yosys plugin.
