Spencer Oliver 3c69eee9ef cortex m3: add cortex_m3 reset_config cmd
This new cmd adds the ability to choose the Cortex-M3
reset method used.
It defaults to using SRST for reset if available otherwise
it falls back to using NVIC VECTRESET. This is known to work
on all cores.

Move any luminary specific reset handling to the stellaris cfg file.

Mike Dunn 7682877c8c xscale documentation: vector table handling
Hi everyone.  I noticed some incorrect information in the user manual
regarding how the vector table is handled on the xscale, so for your
consideration, here's a short patch that corrects it, and adds a
little more detail I thought might be helpful.

The documentation states that OpenOCD does not attempt to synchronize
the vector tables in memory with those stored in the "mini instruction
cache".  In fact, on each resume it does copy from memory to the cache
all entries in the high and low tables that were not previously
defined using the 'xscale vector_table' command. (In
src/target/xscale.c, see xscale_update_vectors(), which is invoked by
xscale_resume().)  I take advantage of this during Linux boot-up.  The
extra detail describes in general terms how I do this.

Corrections, comments are of course gratefully received.

Thanks,
Mike

David Brownell 93f2afa45f initial "transport" framework
This adds the guts of a transport framework with initialization,
which should work with current JTAG-only configurations (tested
with FT2232).

Each debug adapter can declare the transports it supports, and
exactly one transport is initialized.  (with its commands) in
any given OpenOCD session.

  * Define a new "struct transport with init hooks and a few
 "transport"  subcommands to support it:

     "list" ... list the transports configured (just "jtag" for now)
     "select" ... makes the debug session use that transport
     "init" ... initializes the selected transport (internal)

  * "interface_transports" ... declares transports the current interface
    can support.  (Some will do this from C code instead, when there are
    no hardware versioning (or other) issues to prevent it.

Plus some FT2232 tweaks, including a few to streamline upcoming
support for an SWD transport (initially for Luminary adapters).

Eventually src/jtag should probably become src/transport, moving
jtag-specific stuff  to transport/jtag.

David Brownell 591e0bbab9 split "interface" commands from "jtag" ones
We'll need to be able to work with debug adapter interfaces (drivers)
even when they're not used for JTAG ... for example, while there are
multi-transport drivers which support JTAG *and* several other
transports (or just one more, like SWD) there are also adapters
with more limited goals (and no JTAG support at all).

Start decoupling the two concepts ("debug adapter driver", "jtag")
by having two command groups, which initialize separately.

This will help us support OpenOCD sessions using only non-JTAG
transports, in which JTAG commands should not be registered.
Update docs to mention that the JTAG, SVF, and XSVF commands
won't work without a JTAG transport.

Note that at least commands working with SRST are still inappropriately
coupled  to JTAG ... inappropriate because (a) SRST is not part of the
JTAG standard, for all that many platforms (like ARM) expect it; and also
(b) because they're used with non-JTAG debug and programming interfaces,
too.  They should perhaps become generic "interface" operations at some
point.  (Similarly with the clock rate to be used by a given adapter.)

David Brownell c6e323b983 doc: not all debug adapters are "dongles"
Talk more about "debug adapters" instead of only "dongles".  Not all
adapters are discrete widgets; some are integrated onto boards.  If
we only talk about "dongles" we rule out many valid setups, and help
confuse some users (who may be using Dongle-free environments).

Also start bringing out the point that JTAG isn't the only transport
protocol, even though OpenOCD historically presumes "all is JTAG".
(Not all debug adapters are JTAG adapters, or JTAG-only adapters.)

Plus a few minor fixes (spelling etc) in the vicinity of those changes,
and updates about FT2232H clocking issues (they can go faster than the
older chips, and can support adaptive clocking).

David Brownell ec297e4bf1 Fix Luminary FT2232 layout docs/configs
Most of this patch updates documentation and comments for various
Luminary boards, supporting two bug fixes by helping to make sense
of the current mess:

 - Recent rev C lm3s811 eval boards didn't work.  They must use
   the ICDI layout, which sets up some signals that the older
   boards didn't need.  This is actually safe and appropriate
   for *all* recent boards ... so just make "luminary.cfg" use
   the ICDI layout.

 - "luminary-lm3s811.cfg", was previously unusable!  No VID/PID;
   and the wrong vendor string.  Make it work, but reserve it
   for older boards where the ICDI layout is wrong.

 - Default the LM3748 eval board to "luminary.cfg", like the
   other boards.  If someone uses an external JTAG adapter, all
   boards will use the same workaround (override that default).

The difference between the two FT2232 layouts is that eventually
the EVB layout will fail cleanly when asked to enable SWO trace,
but the ICDI layout will as cleanly be able to enable it.  Folk
using "luminary.cfg" with Rev B boards won't see anything going
wrong until SWO support is (someday) added.

In conjunction with manual register setup, this lets the ETM trigger
cause entry to debug state.   It should make it easier to test and
bugfix the ETM code, by enabling non-trace usage and isolating bugs
specific to thef ETM support.  (One current issue being that trace
data collection using the ETB doesn't yet behave.)

For example, many ARM9 cores with an ETM should be able to implement
four more (simple) breakpoints and two more (simple) watchpoints than
the EmbeddedICE supports.  Or, they should be able to support complex
breakpoints, incorporating ETM sequencer, counters, and/or subroutine

David Brownell 61af6a6816 target: MMU-aware init for memory read/write
Start switching MMU handling over to a more sensible scheme.
Having an mmu() method enables MMU-aware behaviors.  Not having
one kicks in simpler ones, with no distinction between virtual
and physical addresses.

Currently only a handful of targets have methods to read/write
physical memory:  just arm720, arm920, and arm926.  They should
all initialize OK now, but the arm*20 parts don't do the "extra"
stuff arm926 does (which should arguably be target-generic).

it be a normal "for" loop, instead of scattering its three parts

David Brownell 3e6f9e8d1e target.cfg: remove "-work-area-virt 0"
The semantics of "-work-area-virt 0" (or phys) changed with
the patch to require specifying physical or virtrual work
area addresses.  Specifying zero was previously a NOP.  Now
it means that address zero is valid.

This patch addresses three related issues:

 - MMU-less processors should never specify work-area-virt;
   remove those specifications.  Such processors include
   ARM7TDMI, Cortex-M3, and ARM966.

 - MMU-equipped processors *can* specify work-area-virt...
   but zero won't be appropriate, except in mischievous
   contexts (which hide null pointer exceptions).

   Remove those specs from those processors too.  If any of
   those mappings is valid, someone will need to submit a
   patch adding it ... along with a comment saying what OS
   provides the mapping, and in which context.  Example,
   say "works with Linux 2.6.30+, in kernel mode".  (Note
   that ARM Linux doesn't map kernel memory to zero ...)

 - Clarify docs on that "-virt" and other work area stuff.

Seems to me work-area-virt is quite problematic; not every
operating system provides such static mappings; if they do,
they're not in every MMU context...

David Brownell 7556a93aed XSVF: use svf_add_statemove()
XSVF improvements:

 - Layer parts of XSVF directly over SVF, calling svf_add_statemove()
   instead of expecting jtag_add_statemove() to conform to the SVF/XSVF
   requirements (which it doesn't).

   This should improve XSTATE handling a lot; it removes most users of
   jtag_add_statemove(), and the comments about how it should really do
   what svf_add_statemove() does.

 - Update XSTATE logic to be a closer match to the XSVF spec.  The main
   open issue here is (still) that this implementation doesn't know how
   to build and submit paths from single-state transitions ... but now
   it will report that error case.

 - Update the User's Guide to mention the two utility scripts for
   working with XSVF, and to mention the five extension opcodes.

Handling of state transition paths is, overall, still a mess.  I think
they should all be specified as paths not unlike SVF uses, and compiled
to the bitstrings later ... so that we can actually make sense of the
paths.  (And see the extra clocks, detours through RUN, etc.)

David Brownell bc792857a5 doc updates to match "help" better
This makes the documentation a closer match to "help" output:

 - "pathmove" somehow was not documented in the User's Guide

 - "jtag_nsrst_assert_width" and "jtag_ntrst_assert_width"
   are new; both needed descriptions.

 - Removed two undocumented and fairly useless script mechanisms:
    * production/production_info/production_test ... using it,
      requires replacing everything; so having it adds no value.
    * cpu ... way out of date; hopeless to keep that current

Note that anyone using that "production" stuff already defines
their own procedures, and can keep using them with no change.

dbrownell 7c7467b34f Add a new JTAG "setup" event; use for better DaVinci ICEpick support.
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

dbrownell 1033633321 Minor ETB and ETM bugfixes and doc updates
- 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.

dbrownell 2e210ee48f Streamline Capture-IR handling and integrity test.
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.
   It's likely a bug, but maybe not; else this should be an error.
   Improve the related diagnostics to say which TAP is affected.

And associated minor fixes/cleanups to comments and diagnostics.

dbrownell 22045fa6f2 When setting up an ETM, cache its ETM_CONFIG register. Then
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.

dbrownell 9536577c02 Minor fixes to NAND code and docs
Erase logic:
 - command invocation
    + treat "nand erase N" (no offset/length) as "erase whole chip N"
    + catch a few more bogus parameter cases, like length == 0 (sigh)
 - nand_erase() should be static
 - on error
    + say which block failed, and if it was a bad block
    + don't give up after the first error; try to erase the rest
 - on success, say which nand device was erased (name isn't unique)

Device list ("nand list"):
 - say how many blocks there are
 - split summary into two lines
 - give example in the docs

Doc tweaks:
 - Use @option{...} for DaVinci's supported hardware ECC options

For the record, I've observed that _sometimes_ erasing bad blocks causes
failure reports, and that manufacturer bad block markers aren't always
erasable (even when erasing their blocks doesn't trigger an error report).

Initial support for disassembling Thumb2 code.  This works only for
Cortex-M3 cores so far.  Eventually other cores will also need Thumb2
support ... but they don't yet support any kind of disassembly.

 - Update the 16-bit Thumb decoder:
 
     * Understand CPS, REV*, SETEND, {U,S}XT{B,H} opcodes added
       by ARMv6.  (It already seems to treat CPY as MOV.)

     * Understand CB, CBNZ, WFI, IT, and other opcodes added by
       in Thumb2.

 - A new Thumb2 instruction decode routine is provided.
 
     * This has a different signature:  pass the target, not the
       instruction, so it can fetch a second halfword when needed.  
       The instruction size is likewise returned to the caller.

     * 32-bit instructions are recognized but not yet decoded.
   
 - Start using the current "UAL" syntax in some cases.  "SWI" is
   renamed as "SVC"; "LDMIA" as "LDM"; "STMIA" as "STM".

 - Define a new "cortex_m3 disassemble addr count" command to give
   access to this disassembly.

Sanity checked against "objdump -d" output; a bunch of the new
instructions checked out fine.

Warn when people (or scripts) use numeric identifiers for TAPs,
instead of dotted.name values.  We want this usage to go away,
so that for example adding more TAPs doesn't cause config scripts
to break because some sequence number changed.

It's been deprecated since late 2008, but putting a warning on
this should help us remove it (say, in June 2010) by helping to
phase out old (ab)usage in config scripts.

Other than in various config files, the only code expecting such
a number was the almost unused str9xpec driver.  This code was
changed to use the TAP it was passed, instead of making its own
dubious lookup and ignoring that TAP.

fine for personal use, of course.)

   filling in some missing holes along the way:

     * Suggest "project directory" structure
     * Introduce new term, "user config" file (openocd.cfg)
     * Talk about more options for openocd.cfg contents
     * ... and about creating new config files

    output going into the server output/log instead of just the

    with descriptions of all the supported image file formats,
    so every image command can just reference that section.

	as a bugfix.  (Old behavior:  restore defaults, even if
	they weren't previously active.)

  (2)	Only the behaviors that were explicitly specified get
  	changed.  (Old behavior:  everything else gets reset to
	the "default".)  So for example you can now specify SRST
	drive requirements without saying anything about the
	three unrelated topics you previously had to specify.

That second one might cause confusion for any configs that end
up calling "reset_config" twice, so it will deserve to be called
out in the release notes.  (There were no such configurations in
the current OpenOCD source tree.)

Update docs accordingly.  Note that at least some versions of
the texi-to-html tools can't handle "@xref{with spaces}", but
those work properly in PDF and in the info files.

Provide basic documentation for some of the other flash drivers.

 avr ... looks incomplete, may work with one AVR8 microcontroller
 ecosflash ... can't find docs
 lpc288x ... an NXP part, driver seems lpc2888-specific
 ocl ... some arm7/arm9 thing, can't find docs
 pic32mx ... looks incomplete, for PIC32MX (MIPS 4K) devices
 tms470 ... for TI TMS470 parts

Still seems to be mostly arm7tdmi... several of these have no
users in the current tree.

Start converting the architecture-specific commands to @deffn format,
reviewing against the code.

  * armv4_5 disassemble ... now documented; although Jazelle code
    is not handled

  * It's "armv4_5 core_state" not "core_mode"; although Jazelle state
    is not handled

  * arm7/9 "debug" commands ... now with other arm7_9 commands, no
    longer in a separate section

  * arm926ejs cp15 ... previous description was broken, it matched
    the code for arm920t instead

  * Have separate subsections for ARMv4/ARMv5, ARMv6, and ARMv7; the
    latter are new
    
  * Move core-specific descriptions into sub-subsections under those
    architectures; XScale and ARM11 descriptions are new

The new XScale and ARM11 command descriptions surely need elaboration
and review.  ARM CP15 operation descriptions in general seem to be
confused and incomplete.

Continue updating the NOR flash coverage to use @deffn syntax, so the
commands have more consistent presentation and formatting.  This
reorganizes information and updates its presentation, except where
the information didn't really match the code.

This patch updates the main commands, and finishes making the section
structure parallel the NAND presentation.  Of note:

 - The "flash fill[whb] addr value length" commands are now documented.

 - The "flash bank" command is now presented much earlier

 - Explicit mention is made that NOR flash should be read using just
   standard memory access commands, like "mdw" and "dump_image".
