yep. https://libre-riscv.org/openpower/isa/

took about 5 hours but there's now information missing, i cut too much out.
the parser took about a day to get into shape.
putting in the decoder and a prototype regfile, another day.
first succesful instruction was today.
estimated... maybe... 3-4 more days and we should have the complete
set of integer instructions done. not speed-optimised at all.
quirks such as what various SPRs mean and do, maybe another 2-3 days.
