I attended the OpenPower virtual coffee meeting, there was an interesting
suggestion to see if we could move to a later tapeout than october, to
avoid burnout due to deadline crunch.

I also weighed in on nmigen signed/unsigned sign extension/zero
extension/truncation operators:
https://github.com/nmigen/nmigen/issues/381

still slowly getting through the load/store unit stuff, progress may be a
little slow since I have a bunch of stuff I need to do at home as well.
