it worked!
https://git.libre-soc.org/?p=soc.git;a=blob;f=src/soc/debug/test/openocd_test.sh;hb=HEAD

i adjusted the test to no longer create the client-side TCP
connection, but left the DMI nmigen simulation and the Wishbone nmigen
SRAM still connected to the nmigen JTAG TAP adapter.
https://git.libre-soc.org/?p=soc.git;a=blob;f=src/soc/debug/test/test_jtag_tap_srv.py;hb=HEAD#l201

i then ran the openocd code against that and it worked.

*now* with the openocd svf command tested, i can go back to the litex
sim.py, confident that the openocd side is working (and the C4M JTAG
TAP adapter) and investigate why that's not responding with the
correct DMI responses.
