Dean Glazeski 3ac2a44041 AT91SAM9 NAND flash driver.
This creates the TCL interface for configuring an AT91SAM9 NAND flash
controller and implements the necessary functions to correctly work with
a NAND flash device connected to the chip.  This includes updates to the
driver list and the Makefile.am to support building the driver and also
houses the documentation update in openocd.texi.

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.

David Brownell 81aec6be04 ARM: list number of HW breakpoints/watchpoints
When starting up, say how many hardware breakpoints and watchpoints
are available on various targets.

This makes it easier to tell GDB how many of those resources exist.
Its remote protocol currently has no way to ask OpenOCD for that
information, so it must configured by hand (or not at all).

Update the docs to mention this; remove obsolete "don't do this" info.
Presentation of GDB setup information is still a mess, but at least

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 d47764ff71 ETM: start support for ETMv2+
ARM11 and newer cores include updated ETM modules.  Recognize
their version codes and some key config differences.  Sanity
checked on an OMAP2, with an ETM11RV r0p1 (ETMv3.1).

This still handles only scan chain 6, with at most 128 registers.
Newer cores (mostly, Cortex) will need to use the DAP instead.

Note that the newer ETM modules don't quite fit the quirky config
model of the older ones ... having more port widths is easy, but
the modes aren't the same.  That still needs to change.

Fix a curious bug ... how did the register cache NOT get saved??

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.

David Brownell d70d9634bf finish removing deprecated/obsolete commands
It's been about a year since these were deprecated and, in most
cases, removed.  There's no point in carrying that documentation,
or backwards compatibility for "jtag_device" and "jtag_speed",
around forever.  (Or a few remnants of obsolete code...)

Removed a few obsolete uses of "jtag_speed":

 - The Calao stuff hasn't worked since July 2008.  (Those Atmel
   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
   1 MHz on typical HW).
 - In general, speed controls need to live in board.cfg files (or
   sometimes target.cfg files), not interface.cfg ...

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.)

dbrownell b1f7b35983 Change version labels to work better with GIT
- 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!)

    Open On-Chip Debugger 0.3.0-in-development (2009-10-05-01:39) svn:exported

2009-10-07 05:43:05 +00:00
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.

This patch adds support for the Luminary Micro LM3S9B90 target and
LM3S9B92 Evaluation Kit.  These kits include a new ft2232 adapter, the
Luminary In-Circuit Debug Interface (ICDI) Board, so this is added as a
new ft2232 layout called "luminary_icdi".

zwelch 0894ae214a David Brownell <david-b@pacbell.net>:
Add "jtag names" command, mirroring "target names" but returning
TAP names instead of target names.  This starts letting TAPs be
manipulated in scripts ... much like what works now for targets.

It's a bit limited just yet, since "jtag cget $TAPNAME" doesn't
expose all TAP attributes.  "$TARGETNAME cget" is more functional.

zwelch f0fd28a66c David Brownell <david-b@pacbell.net>:
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.

This should be my last significant update of the User's Guide for
this release.  Mostly it's a rework of the config file chapter's
presentation of board and target config files.

 - Give the new path for scripts!
 - Move board-config material out of the target-config section
 - Add more board-config info, notably for reset-init events
 - Link out of the board-config section to NAND, NOR, and Reset chapters
 - Emphasize target input vs. output naming conventions
 - Other textual improvements

Plus some other updates, like adding my copyright (now that I've
basically rewritten much of this).

 - Various @cindex improvements

 - Cross reference the command line options in a few spots,
   notably for @command{debug_level}

 - Clean the config file guidelines a bit:
    * They're for all users, not just integrators
    * Reference the interface config chapter
    * Don't emphasize command line usage here
    * Tweak board and target config introductory text

Plus two minor bits of cleanup:  remove most date references,
and refer to the reader as "you" not "the user".

zwelch 011e9b85b1 David Brownell <david-b@pacbell.net>:
Distributing FTDI's "ftd2xx" library with OpenOCD violates the
OpenOCD license (GNU GPLv2 with no exceptions).

Make that clear where that build option is presented, and don't
describe the FTDI libraries as an option for any packager.  (It's
fine for personal use, of course.)

Plus some related clarifications:  libftdi version 0.16 for the
new FT2232H chips (for RTCK and high speed USB); the Amontec
drivers are just ftd2xx variants.

Doc update:  say "jtag newtap ... -disable" records the

Matching code updates.  Now we can be sure that the
"enabled" flag value is correct after JTAG resets.

OpenOCD doesn't actually *need* to be keeping all TCP ports
active ... creating security issues in some network configs.

Instead, let config file specify e.g. "tcl_port 0" (or gdb_port,
telnet_port) to disable that particular remote access method.

Move the discussion of the "scan_chain" command up to go with

parallel, which will be something of an aid to understanding
that they are different (and how).

zwelch 72687f227a David Brownell <david-b@pacbell.net>:
Rework the "Simple Configuration Files" chapter so it's more
of a quick-start "how to set up your project" tutorial:

 - Say how to hook up the JTAG adapter.  This will help new
   users, and in any case is worth spelling out somewhere.

 - Streamline the previous rather haphazard presentation,
   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
     * Add new topic, project-specific utilities (+examples)

 - Remove too-short, yet duplicative, chapter 19

Nudge packagers a bit more strongly to send patches (including
config files) upstream.

Update "arm9tdmi vector_catch" command description to highlight both
use cases (display configuration, or first change that config) and
to explain a bit more about what this is:  an alternative to using
hardware breakpoint resources.

Note that I tried this on an arm920t, but it didn't work.  Set bits,
then examined them and they weren't set.  And it didn't seem to act
as if vector triggering was noticed, either.

Also some minor unrelated tweaks:  @ignore some unused or don't-use
event names; fix a few typos; tweak chip-specific reset descriptions.

Update the "General Commands" (a.k.a. "random stuff") chapter,
and associated chunks of other text:

 - Switch to @deffn and review everything that's documented

 - Improve descriptions of reset events, with reference to
   the setup.tcl code which issues them.

 - Move one zy1000-specific command to that driver's doc.

 - There is no "script" command; remove its doc.

NOTE:  Some things missing from this bit of work are:

 1- Reviewing the code to catch various *missing* functions,
    mostly from "target.c"

 2- Alphabetizing and organizing.  This chapter is a real
    grab-bag with no evident focus or structural principle.

 3- Hole-filling and bugfixing with respect to messaging/logging.
    Example, what principle could possibly justify the tcl command
    output going into the server output/log instead of just the
    telnet session?

 4- Not just for this chapter ... but there should be a section
    with descriptions of all the supported image file formats,
    so every image command can just reference that section.
