* closed a stack of bugs, added to #383 everything needed to focus on
the Oct 2020 180nm tapeout deadline
* sorted out div simulator
* added helper routines to get twi/tdi operational in simulator
* investigated sphinx and embedded diagrams for producing
documentation from the codebase
* got nextpnr-ecp5 compiled (it's awful, btw), tested out versa-ecp5g
with some blinky lights (worked)


* debugging the trap pipeline, got it semi-functional, matching the
simulator (partly).  qemu doesn't work which makes it awkward.

rest of day:

see how it goes.

tasks that we need people to step up and help with:

* MUL pipeline
* DIV pipeline
* SPR pipeline
* TRAP pipeline
* Wishbone Bus connectivity
* XICS interrupts
