--- Comment #3 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
the other thing that occurred to me jacob is that Staf would like to
do scans of IO ports as part of the ASIC test.  this is in c4m jtag
https://gitlab.com/Chips4Makers/c4m-jtag/-/blob/master/c4m/nmigen/jtag/tap.py#L411

therefore we *have* to get the jtag interface operational, where
a direct-to-gdb interface is not a full replacement of all needed
functionality.

with staf's JTAG code having been silicon-proven, and it being necessary
to add, time spent on this right now is effectively time wasted when there
are much higher priority things to do.

i _like_ the idea - it's just a hell of a lot of redundant work.
