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.

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.

This is minimal patch to support FA526 ARMv4 compatible core.
Since it is very similar to ARM920T I tried to reuse as much
code as possible.
CPU and board configs will follow soon.
git-svn-id: svn://svn.berlios.de/openocd/trunk@2292 b42882b7-edfa-0310-969c-e2dbd0fdcd60
- Move definition of 'struct target_type_s' into new 'target_type.h' file.
- Forward delclaration remains in target.h, with comment pointing to new file.
- Replaces #define with #include in source files.
git-svn-id: svn://svn.berlios.de/openocd/trunk@1971 b42882b7-edfa-0310-969c-e2dbd0fdcd60
- use continuations to break long lines of variable assignments
- makes these variables more patch-friendly and conform to style guide
git-svn-id: svn://svn.berlios.de/openocd/trunk@1970 b42882b7-edfa-0310-969c-e2dbd0fdcd60
- Move src/target/{interface,target,board,test}/ into src/tcl/

already required autoconf 2.59 (circa 2006), so there is no reason to
support versions of automake older than 1.6 (circa 2002).
The first part of this patch upgrades the configure.in script:
1. Use current calling conventions for the AC_INIT and
AM_INIT_AUTOMAKE macros, bringing their usage up-to-date with
the version of autoconf already specified by AC_PREREQ.
2. Add AC_CONFIG_SRCDIR macro, required by new version of AC_INIT.
3. Automatically enable all of automake's warnings except Makefile
portability (which OpenOCD violates by using GNU make's $(wildcard)).
[[ While automake has its own -Werror option, I did not enabled it
due to existing warnings. ]]
4. Add the missing AM_PROG_C_O check, required by the build rules for
openocd.o in src/Makefile.am.
5. Adjust version number to show progress toward the next release.
6. Include a bug reporting e-mail address to direct users to this list.
This patch makes the following adjustments to the Makefile.am files:
1. Update AUTOMAKE_OPTIONS to require automake version 1.6
2. Rewrite all deprecated INCLUDES assignments as AM_CPPFLAGS
3. Clean-up all AM_CPPFLAGS declarations to be patch-friendly.
4. Remove vestigial references to $(all_includes)
5. Remove erroneous references to @CPPFLAGS@ (only use AM_CPPFLAGS)
6. Remove unused -I and -D directives in helper/, flash/, target/

Added support for accessport ROM table identification, dap command.

from pre/post_reset event scripts. Adding the second parameter was
a mistake seen in retrospect. this gives precise control in post_reset
for *when* the post reset speed is set. The pre_reset event was
added *after* the second parameter to jtag_khz/speed
- the target implementations no longer gets involved in the reset mode
scheme. Either they reset a target into a halted mode or not.
target_process_reset()
detects if the reset halt failed or not.
- tcl target event names are now target_N_name. Mainly internal
at this early stage, but best to get the naming right now.
- added hardcoded reset modes from gdb_server.c. I don't know precisely what
these defaults should be or if it should be made configurable. Perhaps some
hardcoded defaults will do for now and it can be made configurable later.
- bugfix in cortex_m3.c for reset_run_and_xxx?
- issue syntax error upon obsolete argument in target command instead of
printing message that will surely drown in the log

This patch just uses the command.c interface to create tcl commands for the root level commands and avoids a bit of the "TCL" bleed into the rest of the openocd code.
Multilevel commands also supported.

for a bit more info before I can tell with confidence whether or not
this would have any effect.
- worked on error propagation and output for flash
git-svn-id: svn://svn.berlios.de/openocd/trunk@539 b42882b7-edfa-0310-969c-e2dbd0fdcd60
- added new commands arm11 mrc and arm11 mcr to generate these instructions during debug

arm11
--- Added burst memory transfer mode
This does not explicitly query command execution but rather uses a small
delay produced by the FT2232 on certain TAP commands.
A potential failure of this process is detected afterwards and the
program terminates with an error.
'arm11 memwrite burst disable'
can be used to switch this feature off.
'arm11 memwrite error_fatal disable'
can be used to prevent the program to exit on an memory write error
--- Added support for interrupt breaking via VCR register
Use 'arm11 vcr' command to set.
--- Cleaned up the handling of
halt/resume/step/poll, target->state, target->debug_reason,
target_call_event_callbacks() at least as far as I could guess the
intended behaviour from other targets.
Did some overall positive tests with GDB.
--- Added support for breakpoints
Hardware breakpoints only. All breakpoints will be treated as hardware
breakpoints.
All ARM11's seem to have at least 6 hardware breakpoints.
--- Stepping over BKPT added
Modification to PC without touching the target.
--- Stepping over a B or BL to self will do nothing

- added XScale debug handler binary to repository
- added Thumb disassembling (thanks to Vincent Palatin for this patch)
- added support for non-CFI compatible flashes to cfi driver (currently only SST39VFxxx devices supported)
This checkin is experimental, not suitable for general use
git-svn-id: svn://svn.berlios.de/openocd/trunk@155 b42882b7-edfa-0310-969c-e2dbd0fdcd60
- fixed some compiler warnigns in amt_jtagaccel.c, bitbang.c, parport.c
- free working area and register stuff if str7x block write algorithm failed
- check PC after exiting a target algorithm in armv4_5.c
git-svn-id: svn://svn.berlios.de/openocd/trunk@135 b42882b7-edfa-0310-969c-e2dbd0fdcd60

git-svn-id: svn://svn.berlios.de/openocd/trunk@81 b42882b7-edfa-0310-969c-e2dbd0fdcd60
- OpenOCD now includes the ability to diassemble instructions on its own (only ARM for now, Thumb might follow).
The command is "armv4_5 disassemble <address> <count> ['thumb']" (thumb is currently unsupported).
I've compared the produced disassembly against GDB/GNU Objdump output, and it seems to be correct, but there may still be some bugs left.
