- ETB
* report _actual_ hardware status, not just expected status
* add a missing diagnostic on a potential ETB setup error
* prefix any diagnostics with "ETB"
- ETM
* make "etm status" show ETM hardware status too, instead of
just traceport status (which previously was fake, sigh)
- Docs
* flesh out "etm tracemode" docs a bit
* clarify "etm status" ... previously it was traceport status
* explain "etm trigger_percent" as a *traceport* option
ETM+ETB tracing still isn't behaving, but now I can see that part of
the reason is that the ETB turns itself off almost immediately after
being enabled, and before collecting any data.

only expose the registers which are actually present. They
could be missing for two basic reasons:
- This version might not support them at all; e.g. ETMv1.1
doesn't have some control/status registers. (My sample of
ARM9 boards shows all with ETMv1.3 support, FWIW.)
- The configuration on this chip may not populate as many
registers as possible; e.g. only two data value comparators
instead of eight.
Includes a bugfix in the "etm info" command: only one of the
two registers is missing on older silicon, so show the first
one before bailing.
Update ETM usage docs to explain that those registers need to be
written to configure what is traced, and that some ETM configs
are not yet handled. Also, give some examples of the kinds of
constrained trace which could be arranged.

system, removes 20 non-existent registers ... but still includes
over 45 (!) ETM registers which don't even exist there ...
- Integrate the various tables to get one struct per register
- Get rid of needless per-register dynamic allocation
- Double check list of registers:
* Remove sixteen (!) non-registers for data comparators
* Remove four registers that imply newer ETM than we support
* Change some names to match current architecture specs
- Handle more register info
* some are write-only
* some are read-only
* record which versions have them, just in case
- Reorganize the registers to facilitate removing the extras
* group e.g. comparator/counter #N registers together
* add and use lookup-by-ID

- Add a header comment
- Line up the ETM context struct, pack it a bit
- Remove unused context_id (this doesn't support ETMv2 yet)
- Make most functions static
- Remove unused string table and other needless lines of code
- Correct "tracemode" helptext
Also provide and use an etm_reg_lookup() to find entries in the ETM
register cache. This will help cope with corrected contents of that
cache, which doesn't include entires for non-existent registers.

this fn has something to do with the queue, which it does not as such.

Provide basic documentation on the ARM ETM and ETB trace commands.
Fix minor goofs in registration of the ETM commands; and whitespace
issues in the proof-of-concept oocd_trace code. (Plus include a
ref to Dominic's email saying that it's just proof-of-concept code.)
Note that I'm still not sure whether the ETM support works. But
documenting how it's expected to work should help sort out which
behaviors are bugs, which will help get bugs patched.
ZW: whitespace changes were split out of this patch but will follow.

the key command_*() helper functions, fixng the bugs that turned up.
Several of these bugs were from misuse of PRIi64; that's for 64-bit
integers, NOT for "long long" or "u64" (which work best with %lld).

More precise, less code.
- removed unused code in fileio.c
- Windows should now find debug_handler.bin
git-svn-id: svn://svn.berlios.de/openocd/trunk@390 b42882b7-edfa-0310-969c-e2dbd0fdcd60
- bugfix in server.c
- removed unused parameter from jtag_add_ir_scan et al. This
wasn't necessary in hindsight but anyway.
- arm11 source committed but not not in Makefile.am/target.c for now.

flash verify_image and flash erase_address.
- added patch for new parport_write_on_exit command.
Even this patch will fix some memory leaks.
(thanks too oyvind and Spen for these patches)

- use 'etm trigger_percent' setting when programming ETB trigger count
- fixed some small bugs in ETM trace analysis
- fixed minor bug in flash writing (thanks to Pavel Chromy)

- added OpenOCD+trace as an ETM capture driver example implementation
- new usbprog driver (thanks to Benedikt Sauter)

- make OpenOCD listen for WM_QUIT messages on windows (thanks to Pavel Chromy)
- register at_exit handler to do necessary unregistering (thanks to Pavel Chromy)
- added dummy ETM capture driver to allow ETM to be registered without a capture driver
