ah i didn't have a shutdown command, but yes.

i'm running into difficulties trying to send DMI-ADDR and DMI-READ
commands.  trying to debug the massive vcd files created by litex
sim.py is a bit much, so i'm going to go ahead with the "compatible"
jtagremote client-server code, then connect openocd with an SVF file
to a *small* test program.

this will drastically cut down the debug surface and allow me to test
openocd against one of the existing nmigen unit tests.

*then* once i have that debugged i can go back to trying the exact
same openocd svf test against litex sim.py.
