      simplify XScale debug handler installation · 5e837387
      David Brownell authored 
      
Load the XScale debug handler from the read-only data section
instead of from a separate file that can get lost or garbaged.
This eliminates installation and versioning issues, and also
speeds up reset handling a bit.

Plus some minor bits of cleanup related to loading that handler:
comments about just what this handler does, and check fault codes
while writing it into the mini-icache.

The only behavioral changes should be cleaner failure modes after
errors during handler loading, and being a bit faster.

NOTE:  presumes GNU assembly syntax, with ".incbin"; and ELF,
because of the syntax of the ".size" directive.

      more xscale cleanup (mostly removing JTAG hooks) · 9f6c23f4
      David Brownell authored 
      
Streamline/shrink some needless JTAG stuff:

 - Use #defines for the JTAG instructions; they can't ever change
 - Remove an unused (!) shadow of tap->ir_length
 - Stop using a copy of target->tap
 - Don't bother saving the variant after sanity checking ir_length

Also, make target_create() work as on other targets:  build the
register cache later, making init_target() no longer be a NOP.
Handle malloc failure; remove a comment that was obsoleted by the
not-so-new target syntax.

      Improve jtag_validate_ircapture() diagnostics. · 7a57c316
      dbrownell authored 
      Bugfix the error message so it shows the disliked value, and add
a debug message showing each TAP's IR capture value, all N bits.

This just changes diagnostics ... it still ignores the parameters
given to us at TAP declaration time.

      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

      Minor cleanup to ARM926 debug entry: · 16a7ad57
      dbrownell authored 
       - don't needlessly export this function
 - handle "case 0" debug method-of-entry better (silent by default)

The "case 0" is a valid debug entry mode so it doesn't deserve the
warning int now gets.  But it probably means that OpenOCD confused
itself somehow; or that it confused the ARM9EJS target.
