It depends on the particular target whether it can work with SRST asserted or not, so this belongs to the target config rather than the board config. Also, this allows for simple openocd -f myboard.cfg -c "reset_config connect_assert_srst" command to be used whenever a user feels a need to connect to an unresponsive target.
