+# ARM Debug Interface V5 (ADI_V5) utility
+# ... Mostly for SWJ-DP (not SW-DP or JTAG-DP, since
+# SW-DP and JTAG-DP targets don't need to switch based
+# on which transport is active.
+#
+# declare a JTAG or SWD Debug Access Point (DAP)
+# based on the transport in use with this session.
+# You can't access JTAG ops when SWD is active, etc.
+
+# params are currently what "jtag newtap" uses
+# because OpenOCD internals are still strongly biased
+# to JTAG ....  but for SWD, "irlen" etc are ignored,
+# and the internals work differently
+
+# for now, ignore non-JTAG and non-SWD transports
+# (e.g. initial flash programming via SPI or UART)
+
+# split out "chip" and "tag" so we can someday handle
+# them more uniformly irlen too...)
