David Brownell a42bea654c ARM720: help/usage updates
Deprecate the "pass an instruction opcode" flavor of cp15
access in favor of the "arm mcr ..." and "arm mrc ..."
commands, which offer fewer ways to break things.

Use the same EBNF syntax in the code as for the user's guide.

Update User's Guide to say where to find those magic values
(which table in the ARM920 TRM).

David Brownell b3bf1d12b2 streamline and document helptext mode displays
Most commands are usable only at runtime; so don't bother saying
that, it's noise.  Moreover, tokens like EXEC are cryptic.  Be
more clear: highlight only the commands which may (also) be used
during the config stage, thus matching the docs more closely.
There are

 - Configuration commands (per documentation)
 - And also some commands that valid at *any* time.

Update the docs to note that "help" now shows this mode info.

This also highlighted a few mistakes in command configuration,
mostly commands listed as "valid at any time" which shouldn't
have been.  This just fixes ones I noted when sanity testing.

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.

David Brownell abe8b43755 ETM: add "etm trigger_debug" command
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
entry/exit criteria int criteria used to trigger debug entry.

Nicolas Pitre ed59dfc80a basic ARM semihosting support
Semihosting enables code running on an ARM target to use the
I/O facilities on the host computer. The target application must
be linked against a library that forwards operation requests by
using the SVC instruction that is trapped at the Supervisor Call
vector by the debugger.  The "hosted" library version provided
with CodeSourcery's Sourcery G++ Lite for ARM EABI is one example.

This is currently available for ARM9 processors, but any ARM
variant should be able to support this with little additional work.

Tested using binaries compiled with Sourcery G++ Lite 2009q1-161
and ARM RVCT 3.0.

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).

Also simplify how target_init() loops over all targets by making
it be a normal "for" loop, instead of scattering its three parts
to the four winds.

   targets need to work with a 32KHz core clock after reset until
   board-specific init-reset code sets up the PLL and enables a
   faster JTAg clock.)
 - Parport speed controls don't actually work (tops out at about

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.
