* ARM11: basic watchpoint supportDavid Brownell2009-12-041-1/+2
| | | | | | Use the DPM watchpoint support; remove old incomplete stubs. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM DPM: share debug reason logicDavid Brownell2009-12-031-12/+0
| | | | | | | | | | | | | | | | | | No point in both ARM11 and Cortex-A8 having private copies of the logic sorting out e.g. DBG_REASON_WATCHPOINT. Add and use a shared routine for this ... there's actually a bunch more debug entry logic that could be shared, this is just a start on that. Note that this routine fixes a bug observed in the ARM11 code, where some abort mode quirks were displayed as being an unknown debug reason; and also silences needless ARM11 chatter. Likewise with private copies of DSCR ... add one to the DPM struct. Save it as part of setting DBG_REASON_* so later patches can switch over to using that copy. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: use shared DSCR bit namesDavid Brownell2009-12-031-22/+1
| | | | | | | | | | | | | For the bits now defined in "arm_dpm.h", switch to the shared DSCR_* symbol and remove the ARM11_DSCR_* version. Define DSCR_INT_DIS and use it instead of the ARM11_DSCR_* sibling symbol. (Note: for both ARM11 and Cortex-A8, this should arguably be enabled by default when single stepping.) Remove some other unused declarations in "arm11.h". Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* change #include "armv4_5.h" to <target/armv4_5.h>Zachary T Welch2009-12-031-1/+1
| | | | | | | | | | | | Changes from the flat namespace to heirarchical one. Instead of writing: #include "armv4_5.h" the following form should be used. #include <target/armv4_5.h> The exception is from .c files in the same directory.
* change #include "arm_dpm.h" to <target/arm_dpm.h>Zachary T Welch2009-12-031-1/+1
| | | | | | | | | | | | Changes from the flat namespace to heirarchical one. Instead of writing: #include "arm_dpm.h" the following form should be used. #include <target/arm_dpm.h> The exception is from .c files in the same directory.
* ARM11: don't expose DSCRDavid Brownell2009-12-021-14/+0
| | | | | | | | | | | Remove the remaining extra copy of DSCR, and the register cache of which it was a part. That cache wasn't a very safe, or even necessary, idea; it was essentialy letting debugger-private state be manipulated by Tcl code that couldn't know how to do it right. This makes the "reg" output of an ARM11 resemble what most other ARM cores produce ... forward motion in the "make ARM11 work like the rest of the ARM cores" Jihad!
* ARM11: store a clean copy of DSCRDavid Brownell2009-12-021-2/+1
| | | | | | | Just store a clean copy of DSCR in the per-CPU struct, so we trivially pass a pointer to a recent copy. This replaces the previous "last_dscr" and cleans up most of the related calling conventions ... but it doesn't remove the other DSCR copy.
* ARM11: don't expose WDTRDavid Brownell2009-12-021-1/+4
| | | | | | | | | Don't expose the WDTR register through the register cache any more. If anyone wants Tcl scripts to be able to use DCC based communication with app code in the target, this wouldn't do it. Bugfix: don't trust the Tcl-accessible version of DSCR to flag whether WDTR needs to be restored when resuming.
* ARM11: don't expose RDTRDavid Brownell2009-12-021-1/+4
| | | | | | | | | Don't expose the RDTR register through the register cache any more. If anyone wants Tcl scripts to be able to use DCC based communication with app code in the target, this wouldn't do it. Bugfix: don't trust the Tcl-accessible version of DSCR to flag whether RDTR needs to be restored when resuming.
* ARM11: remove arm11->targetDavid Brownell2009-12-021-8/+1
| | | | | Don't need/want arm11->target; we have arm11->arm.target instead. Also remove some unused watchpoint stuff.
* ARM11: remove old R0..R15/CPSR codeDavid Brownell2009-11-241-3/+2
| | | | | | | | | | | | | | | | This finishes the basic switchover to the new register code, for everything except the debug registers. (And maybe we shouldn't have a cache for *those* which works this way...) The context save/restore code now uses the new code, but it's in a slightly different sequence. That should be fine since the R0/PC/CPSR stuff is all that really matters (and if we can update those, we can update the rest). Now there's no longer a way any code can be confused about which copy of "r1" (etc) to use. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: remove register "history" debug stuffDavid Brownell2009-11-241-9/+0
| | | | | | | | | | | | | | This was a private mechanism to snapshot registers before leaving debug state, and then on reentry to optionally display what changed. It was coupled to the private register cache, which won't be sticking around in that form for much longer. Remove (instead of teaching it how to handle *all* the registers). (The idea is interesting, but we ought to be able to implement this in a generic way. Ideally through Tcl scripts that can automatically be invoked following debug entry...)

* ARM11: implement provider for new DPM interfaceDavid Brownell2009-11-241-0/+4
| | | | | | | This is a very thin layer over some of the current ARM11 debug TAP utilities. The layer isn't yet hooked up. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: remove unused state and exportsDavid Brownell2009-11-221-6/+0
| | | | | | | | | For now there's no point in saving this stuff after examine() checks it out as OK. Ditto exporting symbols that aren't used outside of the module which defines them. In fact, those two things needlessly complicate the code... Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: macro cleanupDavid Brownell2009-11-221-16/+9
| | | | | | | | | | | | | | | | | Make this code look more like the rest of the OpenOCD code. - Use calloc() directly, not NEW() ... and fix some potential memory leaks while we're at it. - Remove FNC_INFO ... it's a NOP that just clutters things, and it's trivial for developers to add tracing as needed. - Replace FNC_INFO_NOTIMPLEMENTED with LOG_WARNING calls; ditto. And stop having those call sites wrongly succeed! - Waste less space with the CHECK_RETVAL() macro. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: remove needless string format #ifdefferyDavid Brownell2009-11-221-10/+0
| | | | | | | | We don't need to use size_t in these places; so it's easy to be rid of the need for this #ifdef and its MS-derived portability problems. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: remove disabled register hooksDavid Brownell2009-11-221-5/+2
| | | | | | | | Minor cleanup of ARM11 register handling: remove disabled register hooks. This should all be handled by shared code, and this stuff is just clutter. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* move ARRAY_SIZE macro to types.hZachary T Welch2009-11-161-2/+0
| | | | | | | | The ARRAY_SIZE macro was defined in several target files, so move it to types.h. This patch also removes two other identical macros: DIM (from jtag.h) and asizeof (from arm11.h).
* ARM11: fixup method tableDavid Brownell2009-11-151-2/+0
| | | | | | | | | Three changes: remove ARM11_HANDLER() in favor of normal structure initialization syntax; fix goofy indentation in that structure; and don't needlessly export arm11_register_commands(), it's only called through that method table. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: revert etmr/etmw commandsDavid Brownell2009-11-131-5/+0
| | | | | | | These aren't desirable, given "standard" ETM support. Also remove the now-unused arm11_find_target(). Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: switch to new "arm" base typeDavid Brownell2009-11-131-3/+9
| | | | | | | | | | This will enable reusing many common ARM utilities, in particular the ETM and ETB support. The ARM11 support can still be much simplified after this patch, though. Note: none of those common utilities kick in yet... Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

| | | | Remove misleading typedef and redundant suffix from struct arm11_register_history.
* arm11: add etmr/etmw registers to access ETM via DBGTAP scan chainMichael Bruck2009-11-101-0/+5
| | | | | | | | First cut of these commands. Øyvind tinkered a bit with the number parsing to bring it up to speed + rebased it. Ready for testing. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* Add private header for ARM11 internals.Zachary T Welch2009-11-081-46/+0
| | | | | | | Reduces confusion about location of associated routines and reduces clutter in the arm11 header. Removes extra whitespace around the lines touched by these changes.
* ARM11: remove exports and forward declsZachary T Welch2009-11-081-55/+0
| | | | | Unneeded exports cause confusion about the module interfaces. Make almost everything static in the arm11.c module.
* target: remove unused interface fn that clutters codeØyvind Harboe2009-11-051-1/+0
| | | | | | | | | The quit entry point was not being invoked. Just a source of confusion at this point. XScale ran 100x reset upon quit, but that code made no sense, wasn't commented and never invoke. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* More MinGW C99 printf complianceRedirect 'Slash' NIL2009-10-171-1/+2
| | | | | | | | Passing "--std=gun99" is unfortunately not sufficient to make current MinGW compilers conform with respect to checking printf format strings. (The C runtime seems not to have problems.) Fix by using a "gnu_printf" format specifier not "printf".
