No, that should be an error. The "what signals" options
are (quoting the manual):
Possible values are ‘none’ (the default), ‘trst_only’,
‘srst_only’ and ‘trst_and_srst’.
The poor debugger would get horribly confused if it had
to operate as if SRST were simultaneously present and
not-present. :)
A good example for how to use this would be a board.cfg
file which is set up for a fully functional JTAG:
# OpenOCD defaults to no SRST or TRST ...
reset_config srst_and_trst separate
# these two are the default drive options
reset_config srst_open_drain trst_push_pull
But then it gets used with a JTAG adapter that doesn't
have TRST, so the openocd.cfg for that hardware stack
could just
reset_config srst_only
