* Added mips_ejtag_drscan_32_out() for optimization.Drasko DRASKOVIC2011-04-051-1/+1

* Added correct endianess treatment for big endian targets. Now it is possible ↵Drasko DRASKOVIC2011-04-051-6/+72
| | | | to use mips_m4k_write_memory() and mips_m4k_read_memory() to correctly set-up SDRAM, as well as bulk data write, which already handled endianess well. Also added correct endianess manipulation in case of fallback from erroneus bulk write to simple write (to avoid byte swapping two times).

* mips: delete kludgy code that modifies data sent to write_memory()Øyvind Harboe2011-03-311-1/+16
| | | | | | | | Could this cause confusion as data sent to write would be flipped and then if the caller subsequently used the data, e.g. a compare mismatch might happen? Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

* bugfix for step <address> mips_m4kAndrew Lyon2011-03-291-0/+4
| | | | | | | | | The patch below fixes step <address> on mips_m4k. Spencer Oliver <spen@spen-soft.co.uk>: The current code is used on all other arch's - is there a underlying issue with those aswell ?
* mips32: add fastdata loader working areaSpencer Oliver2011-01-041-10/+17
| | | | | | | | | | Add a working area that is preserved between calls to mips_m4k_bulk_write_memory - this gives us a speed increase of approx 3kb/sec during flash writes to the pic32mx. This area is released during a resume/reset. Signed-off-by: Spencer Oliver <ntfreak@users.sourceforge.net>
* warnings: fix alignment warningsØyvind Harboe2010-09-201-1/+1

* propagate return status of set_breakpoint() up call chainMike Dunn2010-09-131-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | Hi everyone, I figured since I was poking around in the breakpoint code on other arches, I'd add this change to those arches that don't do it already. This patch propagates the return code of <arch>_set_breakpoint() up the call stack. This ensures that the higher layer breakpoint infrastructure is aware that an error ocurred, in which case the breakpoint is not recorded. Normally I wouldn't touch code that I can't test, but the code is very uniform across architectures, and the change is rather benign, so I figured after careful inspection that it is safe. If the maintainers or others think this is imprudent, the patch can be dropped. Also changed the error code to something more appropriate in two cases where hardware resources are unavailable. Comments and criticisms of course gratefully received. Mike Signed-off-by: Mike Dunn <mikedunn@newsguy.com> Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

* PIC32: add software reset supportSpencer Oliver2010-03-171-3/+23
| | | | | | | | | The PIC32MX does not support the ejtag software reset - it is optional in the ejtag spec. We perform the equivalent using the microchip specific MTAP cmd's. Signed-off-by: Spencer Oliver <ntfreak@users.sourceforge.net>
* MIPS: remove ejtag_srst variantSpencer Oliver2010-03-171-15/+15
| | | | | | | | | | | The mips_m4k_assert_reset has now been restructured so the variant ejtag_srst is not required anymore. The ejtag software reset will be used if the target does not have srst connected. Remove ejtag_srst from docs. Signed-off-by: Spencer Oliver <ntfreak@users.sourceforge.net>
* PIC32: add flash algorithm supportSpencer Oliver2010-03-101-1/+1
| | | | | | | | | | | | | Add flash algorithm support for the PIC32MX. Still a few things todo but this dramatically decreases the programing time, eg. approx programming for 2.5k test file. - without fastload: 60secs - with fastload: 45secs - with fastload and algorithm: 2secs. Add new devices to supported list. Signed-off-by: Spencer Oliver <ntfreak@users.sourceforge.net>
* MIPS: add mips algorithm supportSpencer Oliver2010-02-281-78/+68

* remove target_type register_command callbackZachary T Welch2009-11-241-10/+0
| | | | | | Uses chaining of command_registration structures to eliminate all target_type register_callback routines. Exports the command_handler registration arrays for those target types that are used by others.
* target: create/use register_cache_invalidate()David Brownell2009-11-191-3/+3
| | | | | | | | | | | | | | | Create a generic register_cache_invalidate(), and use it to replace three all-but-identical core-specific routines: - armv4_5_invalidate_core_regs() - armv7m_invalidate_core_regs - mips32_invalidate_core_regs() too. Make cache->num_regs be unsigned, avoiding various errors. Net code shrink and simplification. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* target: no implicit #includes of "register.h"David Brownell2009-11-161-0/+1
| | | | | | | | | | | | Same deal: "register.h" got needlessly included all over the place because of being in a few widely included headers. So take it out of the header files which included it, and put it in files which use it ... reduce needless interdependencies. Also, don't need that extra "types.h" inclusion.

* target: don't implicitly include "breakpoint.h"David Brownell2009-11-161-0/+1
| | | | | | | | | | | Most files in the tree seem to have ended up including this, and *quite* needlessly ... only code implementing or using breakpoints actually needs these declarations. So take it out of the header files which included it, and put it in files which use it ... reduce needless interdependencies. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
