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.

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.

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.

Without some extra delay after releasing SRST, we seemed to
be trying to talk to the TAP before it was ready to respond.

Also, talk about "mainline" not "trunk".
The release.txt and release.sh files need more updates.

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.

chapter on config file guidelines, and give more current "ls" output
to show the available library code.

- 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.

- 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
Open On-Chip Debugger 0.3.0-dev-00282-g7191a4f-dirty (2009-10-05-20:57)
Open On-Chip Debugger 0.3.0 (2009-10-05-20:57)
instead of the previous SVN-specific (even when using git-svn!)

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.

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

- 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.
