2011-08-12mips: fix reading uint32 and uint16 when running on big endian hostStefan Mahr
2011-08-09mips32 : Fixed memory byte accessDrasko DRASKOVIC
Function mips_m4k_write_memory() does endianess byte swap, but this procedure break one byte access (temporary array overwrites content in buffer). As a fix, this endianess swap and buffer affecting is preformed only on hword and word accesses (not on byte access).
2011-08-09mips32: Added CP0 coprocessor R/W routinesDrasko DRASKOVIC
This patch adds MIPS32 CP0 coprocessor R/W routines, as well as adequate commands to use these routines via telnet interface. Now is becomes possible to affect CP0 internal registers and configure CPU directly from OpenOCD.
2011-07-04mips_m4k and arm7_9 : Fix soft bkpt endianess for 16-bit instructionsDrasko DRASKOVIC
The patch fix comparison of target data on the host by using target_buffer_get_u16() to transform current_instr to _host_ endianess before comparison.
2011-07-01mips_m4k : Fix soft breakpoint endianess handlingDrasko DRASKOVIC
In order to compare data read from the target with some marcros or data defined on the host, we must transform this read data from target endianess to host endianess. target_read_memory() gets bytes from target to the host, but keeps them in _target_ endianess. This is OK if we just want to temporary keep this data on the host, like keeping breakpoint->orig_instr. But if we want to use this data for any ispections and comparisons on the host side, we must transform it to _host_ endianess, by using target_buffer_get_u32() function. Currently this transformation is missing, and check current_instr == MIPS32_SDBBP will never pass if target and host endianess differ, because current_instr will be kept in _target_ endianess and MIPS32_SDBBP will be kept in _host_ endianess, The patch fix this issue by using target_buffer_get_u32() to transform current_instr to _host_ endianess before comparison.
2011-06-28mips4k: fix big-endian hosts and host alignment problemsØyvind Harboe
the code was making assumptions about the endianness of the host.
2011-06-01mips: fix some more endian madnessStefan Mahr
2011-04-05Added mips_ejtag_drscan_32_out() for optimization.Drasko DRASKOVIC
2011-04-05Added correct endianess treatment for big endian targets. Now it is possible ↵Drasko DRASKOVIC
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).

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 ?
2011-01-04mips32: add fastdata loader working areaSpencer Oliver
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>

2010-09-13propagate return status of set_breakpoint() up call chainMike Dunn
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>

Same deal: "register.h" got needlessly included all over the place because of being in a few widely included headers.
