David Brownell bc13c12be9 add documentation about reset customization
We added two overridable procedures; document them, and the
two jtag arp_* operations they necessarily expose.

Update the comment about the jtag_init_reset() routine; it's
been obsolete for as long as it's had SRST support.

David Brownell 60e24aa597 make PXA255 targets enumerate sort-of-OK
Startup now mostly works, except that the initial target state
is "unknown" ... previously, it refused to even start.

Getting that far required fixing the ircapture value (which
can never have been correct!) and the default JTAG clock rate,
then providing custom reset script.

The "reset" command is still iffy.  DCSR updates, and loading
the debug handler, report numerous DR/IR capture failures.
But once that's done, "poll" reports that the CPU is halted
(which it shouldn't be, this was "reset run"!), due to the
rather curious reason "target-not-halted".

Summary:  you still can't debug these parts, but it's closer.

David Brownell 6160a946ec add overridable Tcl "init_reset"
This abstracts the "jtag arp_init-reset" call into a method
called from OpenOCD startup and reset processing.

Platforms which have different requirements for how such hard
resets must be performed can now override "init_reset" instead
of needing to rebuild custom hacked versions of the server.

David Brownell 41c1af7c67 initial builds of OSK5912 boards need srst_pulls_trst
This is clearly noted in the hardware spec (section 5.2.3); it
works around a chip erratum:  "If the MPU_RESET signal is used,
it may cause the EMIFS bus to lock."

I seem to have a board with such an initial build.  The chip
is labeled XOMAP.  Presumably, parts without that "X" prefix
(eXperimental) resolve this.

David Brownell a8234af06c prevent abort via polling during jtag_reset
Observed:

  openocd: core.c:318: jtag_checks: Assertion `jtag_trst == 0' failed.

The issue was that nothing disabled background polling during calls
from the TCL shell to "jtag_reset 1 1".  Fix by moving the existing
poll-disable mechanism to the JTAG layer where it belongs, and then
augmenting it to always pay attention to TRST and SRST.

David Brownell 40c9668b70 Stop ignoring most scan chain validation errors
Among other things this causes startup errors to kick in the
fallback "reset harder" logic during server startup.  Comments
are also updated a bit, explaining what the various error paths
signify (in at least my observation).

There's one class of validation error that we can still plausibly
ignore:  when wrong IDCODE values are observed.

This change seems to have helped make an OMAP5912 behave much
more reliably.  There's still some post-reset flakiness, but
it's unrelated to scan verification.

dbrownell cdc33b3808 Force sane SRST and TRST initialization
At least some FT2232 based adapters don't necessarily come up
in the expected state, with SRST and TRST disabled.  Since
other adapters could suffer the same problem, let's avoid
needing to patch every driver and just force *all* adapters
to initialize those values properly at server startup.

Instead of just assuming all IDCODE-deprived TAPs violate the
JTAG spec (they don't!), just require TAPs with such problems
to be declared with proper ircapture/irmask values.  Example,
with mask and value of zero.

dbrownell b1f7b35983 Change version labels to work better with GIT
- The guess-rev.sh script is now a tweaked version of "setlocalversion" as
   seen in Linux, U-Boot, and various other projects.  When it finds source
   control support (git, hg, svn) it uses IDs from there.  Else (specific
   to this project) it reports itself as "-snapshot", e.g. from gitweb.

   I verified this new "guess-rev.sh" script runs under Cygwin.

 - Also update the generic version strings to be like "0.3.0-dev" (during
   development) instead of the very long "0.3.0-in-development".  These also
   show up in the PDF docs.  For better tracking, we might eventually change
   these strings to include the version IDs too.

 - Change the startup banner version strings so they include the guess-rev
   output.  Development and release versions with GIT will be like
