Resolve a "FIX" comment; yes that was superfluous given that the
JTAG core does that check by default. It was also buggy since it
wrote to a stack frame that went away before the write happened!!
Other fixes: remove pointless malloc(); zero-init scan_field_t
values wherever they appear; whitespace scrub; spelling fix.

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.

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.

This abstracts the "jtag arp_init-reset" call into a method

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.

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.

- 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

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

itself somehow; or that it confused the ARM9EJS target.

When the OpenOCD server starts up it records its state as TAP_RESET,
even though it could be anything. Then when it starts to examine
the scan chain, it calls jtag_add_tlr() which sees it doesn't have
any work to do, and so it does nothing. This can make the next
operations fail because they start from the wrong TAP state...
Instead of caring about the current recorded state, always enter
TAP_RESET by forcing five clocks with TMS high.
(NOTE: it seems most other JTAG adapter drivers have this same bug.)

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.

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

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

Enable this by using BKPT to terminate execution instead of "branch

writing to Stellaris flash banks; they affect write timings.
That 12-vs-15 MHz issue is problematic; there's no consolidated doc
showing which chips (and revs!) have which internal oscillator speed.
It's clear that only older silicon had the faster-and-less-accurate
flavor. What's less clear is which chips are "old" like that.
Lightly tested, on a DustDevil part.

For ARMv4/ARMv5:
- better command parameter error checking
- don't require an instruction count; default to one
- recognize thumb function addresses
- make function static
- shorten some too-long lines
For Cortex-M3:
- don't require an instruction count; default to one
With the relevant doc updates.

Nyet done: invoke the thumb2 disassembler on v4/v5,

Unify the handling of the req_srst parameter, and rip out a
large NOP branch and its associated FIXME. (There didn't seem
to be anything that needs fixing; but that was unclear since
the constraints were scattered all over the place not unified.)

Unify the handling of the req_tlr_or_trst parameter. Basically,
JTAG TMS+TCK ops ("TLR") is always used ... unless TRST is a safe
option in this system configuration.
git-svn-id: svn://svn.berlios.de/openocd/trunk@2622 b42882b7-edfa-0310-969c-e2dbd0fdcd60
- Track whether TRST and/or SRST actually change:
* If they're not changing, don't ask the JTAG adapter to do anything!
(JTAG TCK/TMS ops might still be used to enter TAP_RESET though.)
* Don't change their recorded values until after the adapter says it
did so ... so fault paths can't leave corrupt state.
* Detect and report jtag_execute_queue() failure mode
* Only emit messages saying what really changed; this includes adding
an omitted "deasserted TRST" message.
* Only apply delays after deasserting SRST/TRST if we *DID* deassert!
- Messages say "TLR" not "RESET", to be less confusing; there are many
kinds of reset. (Though "TLR" isn't quite ideal either, since it's
the name of the TAP state being entered by TMS+TCK or TRST; it's at
least non-ambiguous in context.)
So the main effect is to do only the work this routine was told to do;
and to have debug messaging make more sense.

reset operations. Maybe they can't; or it's a "not yet" thing.
Note that the assert/deassert operations can't yet trigger for
OMAP3 because resets currently include JTAG reset in all cases,
resetting the ICEpick and thus disabling the TAP for Cortex-A8.

nonfunctional cortex_a8 code with something that at least basically
works (for halt/step/resume, without MMU) even if it is incomplete.
(With tweaks from Øyvind, and cleanup from Dave.)
This code has mainly been developed and tested against R1606, it has
been built and tested against R2294 where it runs but step and resume
commands are broken due to regression (which should be fixed now).
This code is really written for OMAP3530. It doesn't identify debug
resources using generic DAP calls to scan the ROM table, or perform
topology detection. The OMAP3530 DAP exposes two memory access ports:
- Port #0 is connected to L3 interconnect (the main bus) with
passthrough to the L4 EMU bus ... so it will be used for most
memory accesses.
- Port #1 is connected to a dedicated debug bus (L4 EMU), with
access to L4 Wakeup, and holds the ROM table ... so it must
be used for most debug and control operations.
The are some defines to handle this in cortex_a8.c, which should be
replaced with more general code. Having access to another Cortex-A8
implementation would help get that right.
git-svn-id: svn://svn.berlios.de/openocd/trunk@2609 b42882b7-edfa-0310-969c-e2dbd0fdcd60
and seed it with DAP access support using the current ADIv5 code.
(With tweaks and cleanup from Øyvind and Dave.)
The ARMv7-AR architecture manual is not publicly available (even
in subset form like the ARMv7-M spec), so it's hard to distinguish
between the Cortex-A8 implementation and the ARMv7-A architecture.
The register set presumably is architectural, and so it's stored
here; it's like earlier ARMs, with small additions. Ditto the
instruction set, though Thumb2 support is used (extending Thumb
support from ARMv6 with more 32-bit instructions) and there's this
ThumbEE thing too. There is a new "debug monitor" mode, not yet
fully addressed here, to support debugging in environments (like
motor control) where halting debug mode is inadvisable.

ARMv7-M: A5.3.6 Load/store dual or exclusive, table branch
GCC will generate the table branch instructions, usually with inlined
tables that will confuse this disassembler. LDREX and STREX are not
issued by GCC without inline assembly.
This means all Thumb2 instructions implemented by Cortex-M3 can now
be disassembled. Cortex-A8 cores support more Thumb2 instructions,
but most of those aren't yet publicly documented.

- AIRCR_SYSRESETREQ is generic; use it on any system where
SRST won't fly, not just on Stellaris-based ones.
- Reformat and improve comments about the Stellaris quirk; and
xref the only public docs (an email) about the issue.
It seems that *most* Stellaris chips have this problem. Tempest
parts aren't yet in general sampling; and if rev B silicon for
earlier chips exists, it's not very visible yet.

Simplify dumping of register lists by only printing cached values
if they are marked as valid. Most of the time, they are invalid;
so printing *any* value is just misleading.
Note that for ARM7 and ARM9 most EmbeddedICE registers (except for
debug status) could be cached most of the time; and their register
cache isn't maintained properly (many accesses seem to bypass that
cache code).

1. It can only be built with the FTD2XX driver. libftdi supports FT2232H/FT4232H
since version 0.16
2. A speed value of 0 is used as a RTCK request indicator. This clashes with the
valid clock division value 0 that provide the highest fixed clock frequency.
3. The ft2232_speed_div function return the maximum selectable frequency (30MHz)
when RTCK is activated. It should return 0.
4. The ft2232_khz function return ERROR_OK when RTCK is requested even for
devices lacking RTCK support. It should return ERROR_FAIL so the upper driver layers
can detect this and try to fallback to a fixed frequency.
5. FT2232H/FT4232H have a backward compatibility function that divide the clock
by 5 to get the same frequency range as FT2232D. There is no code that disable
this functionality. I can not find anything about if this is enabled or disabled by default.
I think it is safest to actively disable it.

issue with this is that the core debug support uses this
mechanism, then trashes its state over reset. Users can
Work around that (for now) by re-assigning the desired
config after reset.
Also fixes "target halted due to target-not-halted" goof.
When we can't describe the reason using OpenOCD's limited
vocabulary, say "reason undefined" instead of saying it's
not halted.

arrays (error prone) or assume all registers are 32-bits wide (they can
have fewer bits); don't use spaces in register names, so they can be
passed more easily to the "reg" command.
Minor updates for ARM9 vector_catch support: it's an 8-bit value. This
seems to help this core's vector_catch command work a bit better; but its
behavior wih the register cache is still goofy.
