* arm11 error propagation fixesØyvind Harboe2010-07-201-4/+7
| | | | Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* arm11: fix gaffe in no-ack transfersØyvind Harboe2010-06-231-1/+1
| | | | | | | | | | | The code did not transfer the last word in no-ack transfers. The strange thing is that this did not lead to any observable errors. This gaffe was introduced in commit 1f5883ea56cb058221f Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

* jtag: cut down on usage of unintended modification of global end stateØyvind Harboe2010-03-181-1/+1
| | | | | | | | | | | | | jtag_get/set_end_state() is now deprecated. There were lots of places in the code where the end state was unintentionally modified. The big Q is whether there were any places where the intention was to modify the end state. 0.5 is a long way off, so we'll get a fair amount of testing.

* jtag: jtag_add_ir_scan() now takes a single fieldØyvind Harboe2010-03-081-3/+3
| | | | | | | | In the code a single field was all that was ever used. Makes jtag_add_ir_scan() simpler and leaves more complicated stuff to jtag_add_plain_ir_scan(). Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* jtag: retire tap fieldØyvind Harboe2010-03-081-20/+16
| | | | | | | | | | | | | | | | | jtag_add_dr/ir_scan() now takes the tap as the first argument, rather than for each of the fields passed in. The code never exercised the path where there was more than one tap being scanned, who knows if it even worked. This simplifies the implementation and reduces clutter in the calling code. use jtag_add_ir/dr_plain_scan() for more fancy situations. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* arm11: allow minidrivers to implement inner loop of memory writesØyvind Harboe2010-02-221-45/+92
| | | | | | | | | | | | | | | This allows minidrivers to e.g. hardware accelerate memory writes. Same trick as is used for arm7/9 dcc writes. Added error propagation for memory transfer failures in code rearrangement. Also the JTAG end state is not updated until after the memory write run is complete. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* arm11: fix another infinite loop bugØyvind Harboe2010-02-101-4/+23
| | | | | | | | | | | | | reset init would get stuck in an infinite loop when e.g. khz was too high. Added timeout. This is a copy of paste of a number of such bugfixes in the arm11 code. Arm11 code reviewed for further such infinite loop bugs and I couldn't find any more. Xing fingers it's the last one... Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* ARM11: avoid pointless status returnsDavid Brownell2009-12-111-15/+10
| | | | | | | | For some routines that only returned ERROR_OK and where the caller never checked ... don't bother. Remove some noise, and bugfix some comments. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: minor cleanup, mostly ITR commentsDavid Brownell2009-12-111-13/+30
| | | | | | | | | | | | | ITR register handling seemed to be giving me problems, so I updated the comments to better say what the code is trying to do ... and to note the preconditions (one of which seems to be an issue) as listed in the ARM1136 TRM. Also removed the unused "ARM11_TAP_DEFAULT" from the ITR scan code; all the callers already specify an exit path, since this register isn't usable with such vague semantics. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: basic watchpoint supportDavid Brownell2009-12-041-7/+95
| | | | | | Use the DPM watchpoint support; remove old incomplete stubs. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: tweak TAP ops and debuggingDavid Brownell2009-12-041-21/+58
| | | | | | | | | | | | | | | | | | Tweak scanchain 7 debug messaging: - show register addresses in decimal, matching ARM docs; - remove some pointless noise Avoid some needless roundtrips: - skip SCAN_N when SCREG already holds that number (speeds up polling and other common operations) - avoid zeroing vcr twice on resume Show the IR opcode as a label ("RESTART") too; and in decimal, matching ARM docs. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM DPM: share debug reason logicDavid Brownell2009-12-031-44/+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>
* change #include "time_support.h" to <helper/time_support.h>Zachary T Welch2009-12-031-1/+1
| | | | | | | | | | | | Changes from the flat namespace to heirarchical one. Instead of writing: #include "time_support.h" the following form should be used. #include <helper/time_support.h> The exception is from .c files in the same directory.
* ARM11: store a clean copy of DSCRDavid Brownell2009-12-021-14/+13
| | | | | | | 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: remove arm11->targetDavid Brownell2009-12-021-3/+2
| | | | | Don't need/want arm11->target; we have arm11->arm.target instead. Also remove some unused watchpoint stuff.
* ARM DPM: tweak initializationDavid Brownell2009-12-021-2/+11
| | | | | | Move the initial breakpoint/watchpoint disable calls to arm_dpm_initialize(), and start using that routine. This split helps with arm11 support.
* ARM11: fix warning on cygwinDavid Brownell2009-11-291-9/+22
| | | | | | Previous version of JTAG_DEBUG() macro hid this bug. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: fix warning on amd64David Brownell2009-11-281-1/+4
| | | | | | Previous version of JTAG_DEBUG() macro hid this bug. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: fix dbgtap JTAG_DEBUGDavid Brownell2009-11-281-2/+2
| | | | | | | There is no DEBUG() macro; don't call one! Always at least *parse* debug code, to help prevent such errors. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: implement provider for new DPM interfaceDavid Brownell2009-11-241-0/+73
| | | | | | | 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 Brownell2009-11-221-3/+7
| | | | | | | | | 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: do not use dynamic arraysØyvind Harboe2009-11-221-3/+6
| | | | | | Allocate working memory dynamically, caught by checkstack.pl Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* ARM11: remove needless string format #ifdefferyDavid Brownell2009-11-221-5/+7
| | | | | | | | 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>
* target: less implicit inclusion of "etm.h"David Brownell2009-11-161-0/+1
| | | | | | | Don't include it in more headers than necessary; just use it in the few files that actually need it. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* move ARRAY_SIZE macro to types.hZachary T Welch2009-11-161-13/+13
| | | | | | | | 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: revert etmr/etmw commandsDavid Brownell2009-11-131-77/+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 Brownell2009-11-131-0/+2
| | | | | | | | | | 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>
* arm11_sc7_action_t -> struct arm11_sc7_actionZachary T Welch2009-11-131-5/+5
| | | | Remove misleading typedef and redundant suffix from struct arm11_sc7_action.
* arm11_common_t -> struct arm11_commonZachary T Welch2009-11-131-22/+22
| | | | Remove misleading typedef and redundant suffix from struct arm11_common.
* scan_field_t -> struct scan_fieldZachary T Welch2009-11-131-16/+16
| | | | Remove useless structure typedef.
* jtag_tap_t -> struct jtag_tapZachary T Welch2009-11-131-1/+1
| | | | | Search and destroy the jtag_tap_t typedef. This also cleans up a layering violation, removing the declaration from types.h.
* arm11: add etmr/etmw registers to access ETM via DBGTAP scan chainMichael Bruck2009-11-101-0/+76
| | | | | | | | 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 Welch2009-11-081-4/+4
| | | | | | | Reduces confusion about location of associated routines and reduces clutter in the arm11 header. Removes extra whitespace around the lines touched by these changes.
