      Updates for "reset_config": · b83d79a4
      dbrownell authored 
       - revert to previous default: don't talk JTAG during SRST
 - add "srst_nogates" flag, the converse of "srst_gates_jtag"
 - with no args, display the current configuration

And update the User's Guide text with bullet lists to be a bit more clear.

      Add a new JTAG "setup" event; use for better DaVinci ICEpick support. · 7c7467b3
      dbrownell authored 
      The model is that this fires after scanchain verification, when it's
safe to call "jtag tapenable $TAPNAME".  So it will fire as part of
non-error paths of "init" and "reset" command processing.  However it
will *NOT* trigger during "jtag_reset" processing, which skips all
scan chain verification, or after verification errors.

ALSO:
 - switch DaVinci chips to use this new mechanism
 - log TAP activation/deactivation, since their IDCODEs aren't verified
 - unify "enum jtag_event" scripted event notifications
 - remove duplicative JTAG_TAP_EVENT_POST_RESET

      Streamline Capture-IR handling and integrity test. · 2e210ee4
      dbrownell authored 
      Change the handling of the "-ircapture" and "-irmask" parameters
to be slightly more sensible, given that the JTAG spec describes
what is required, and that we already require that conformance in
one place.  IR scan returns some bitstring with LSBs "01".

 - First, provide and use default values that satisfy the IEEE spec.
   Existing TAP configs will override the defaults, but those parms
   are no longer required.

 - Second, warn if any TAP gets set up to violate the JTAG spec.
   It's likely a bug, but maybe not; else this should be an error.
   Improve the related diagnostics to say which TAP is affected.

And associated minor fixes/cleanups to comments and diagnostics.

      Debug message updates: · 0c4b119d
      dbrownell authored 
       - Shrink messaging during resets, primarily by getting rid of
   "nothing happened" noise that hides *useful* information.

 - Improve: the "no IDCODE" message by identifying which tap only
   supports BYPASS; and the TAP event strings.

Related minor code updates:

 - Remove two needless tests when examining the chain:  we know
   we have a TAP, and that all TAPs have names.

 - Clean up two loops, turning "while"s into "for"s which better
   show what's actually being done.

      Minor regression bugfix for the jtag_tap_handle_event() case · 75581ffe

      for disabling TAPs.  We don't actually know how to make any
JRCs which do that yet; but when we do, this will matter.

      Add "jtag names" command, mirroring "target names" but returning
TAP names instead of target names.  This starts letting TAPs be
manipulated in scripts ... much like what works now for targets.

It's a bit limited just yet, since "jtag cget $TAPNAME" doesn't
expose all TAP attributes.  "$TARGETNAME cget" is more functional.

      Fix a bug preventing ICEpick "enable that TAP" code from working:
the "runtest" command wrongly finished with a JTAG reset, discarding
the work the TAP enable handler just finished!  Instead, JTAG should
stay in RUN/IDLE state.

      Extend the internal JTAG event handlers to cover enable/disable,
and use those events to make sure that targets get "examined" if
they were disabled when the scan chain was first set up:

 - Remove "enum jtag_tap_event", merge with "enum jtag_event",
   so C code can now listen for TAP enable/disable events.

 - Report those events so they can trigger callbacks.

 - During startup, make target_examine() register a handler to
   catch ENABLE events for any then-disabled targets.

This fixes bugs like "can't halt target after enabling its TAP".

One class of unresolved bugs:  if the target has an ETM hooked
up to an ETB, nothing activates the ETB.  But starting up the
ETM without access to the ETB registers fails...
