2011-04-01types: write memory now uses constØyvind Harboe
Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
2011-03-31mips: delete kludgy code that modifies data sent to write_memory()Øyvind Harboe
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>

2011-03-31xscale: fix gaffe in phys writeØyvind Harboe
it would *read* instead of *write* to memory when the MMU was disabled. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
2011-03-31target: add -dbgbase option to target configurationØyvind Harboe
Really a Cortex-A specific option, but there is no system in place to support target specific options currently and there has been no need for such a system until now. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
2011-03-29bugfix for step <address> mips_m4kAndrew Lyon
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 ?

2011-03-20dsp563xx_once: fix warning and potential bugØyvind Harboe
I don't think dsp563xx_once_read_register() would ever be called with len==0, but it would have been broken in that case. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
2011-03-17target: allow targets to override memory alignmentMathias K
Targets can implement read/write_buffer to handle alignment.
2011-03-17SYS_WRITE0 fixJohn and Tina Peterson
Problem is, trying to print "Hello, world!\n" just prints endless H's, because r1 is never incremented. One way to fix it would be to add a "++" after "r1".
2011-03-17Fix a bunch of typos.Uwe Hermann
Fix a bunch of typos. Most are in code comments, so nothing should break. UNKOWN_COMMAND and CMD_UNKOWN are not used elsewhere, so correcting the spelling should also not break anything.

2011-02-23cortex_a8: remove dap_ap_sel callsLuca Ellero
add new mem_ap_sel_* functions (as was made for cortex_a9) see commit: 779005f43dc372de937dfd4b445f31d882b98eca Signed-off-by: Luca Ellero <lroluk@gmail.com>
2011-02-21dsp563xx: rudimentary gdb supportMathias K
This patch add rudimentary gdb support. The gdb register list order is corrected. All registers are now 32bit width. Events are send to signalize gdb the current target status. Resume and step function was corrected to consider a modified pc register. Read/write memory now support L memory type, this means a memory with alternating y/x memory words. The memspace variable, used by gdb, is now observed before a default memory access is initiated. Dummy functions for breakpoint and watchpoint are added.
2011-02-17arm_adi_v5: add/move apsel member in struct adiv5_dapLuca Ellero
This patch tries to make some order in "apsel" mess. "dap apsel" command was quite useless (and broken) by itself. With this patch we can use it to select between AHB or APB memory access (previous patch 05ab8bdb813acdcd74afa71d6656c2df816cb230 was somehow broken). - moves member apsel (in struct adiv5_dap) to ap_current - adds apsel member this strange choice is made trying to keep coherence in "dap apsel" command and to keep compatibility with other code (for example cortex_a8). Signed-off-by: Luca Ellero <lroluk@gmail.com>
2011-02-17dsp563xx: minor fixes, code cleanupMathias K
This patch move the dsp563xx_target_create function to the related code block. Also the target examine function was added and the register cache is initialized in a separate function. The missing functionality to invalidate the x memory context on memory writes was also added.
2011-02-17dsp563xx_once: Correct wrong return value on jtag communication errorsMathias K
This patch change the return value on a jtag communication error to TARGET_UNKNOWN because this function should return the current target status and not a error code from the underlying api call. Also the validity of the jtag_status is extended to all static bits in this value.

2011-02-15dsp563xx_once: Correct definition of JTAG_INSTR_CLAMPPhil Fong
I've been working on Rodrigo on adding support to flash Freescale dsp56800e devices and have been looking at the dsp563xx code. I think the define for the JTAG CLAMP instruction in dsp563xx_once.c is incorrect. It should be 0x05 according the Freescale AN2074 (and is also 0x05 in the dsp568xx according to AN1935). It won't actually change anything in OpenOCD since this define is not used anywhere (as far as I can tell).
2011-02-14cortex_a9: move dap_ap_select to arm_avi_v5Luca Ellero
dap_ap_select was used in the code at various points, but that can lead to confusion, without any knowledge of what AP is really selected at some points. Some bugs derive from this (for example md/mw doesn't work well after issueing "dap apsel" command). Moving it to arm_adi_v5.c (using mem_ap_sel* functions instead of mem_ap_*) make the code more clear and more easier to maintain. In the future it should be made "static" to avoid its use outside arm_adi_v5 One further benefit is the various goto has been removed as well Signed-off-by: Luca Ellero <lroluk@gmail.com>

2011-02-10cortex_a9: implement read/write memory through APB-APLuca Ellero
This patch adds read/write capability to memory addresses not accessible through AHB-AP (for example "boot ROM code"). To select AHB or APB, a "dap apsel" command must be issued: dap apsel 0 -> following memory accesses are through AHB dap apsel 1 -> following memory accesses are through APB NOTE: at the moment APB memory accesses are very slow, compared to AHB accesses. Work has to be done to get it faster (for example LDR/STR instead od LDRB/STRB) Signed-off-by: Luca Ellero <lroluk@gmail.com>
2011-02-10cortex_a9: fix dap_ap_select() usageAaron Carroll

2011-01-31Add '-coreid' target option to support multiple cores per TAP.Aaron Carroll
ARM Cortex-A9 multi-core chips expose a single TAP/DAP which connects to both cores. The '-coreid' option selects which core the target should connect to. Note that at present, OpenOCD can connect to either core, but not both simulatenously, until ADI contexts can be shared. Signed-off-by: Aaron Carroll <aaronc@cse.unsw.edu.au>

2011-01-26fix segfault from stack corruption in ahbap_debugport_initAndreas Fritiofson
ahbap_debugport_init was queueing reads to a local stack variable but didn't execute the queue before returning. Since the result of the reads are not used anyway, it's better to pass NULL as the destination instead of a dummy variable. I changed this throughout the function, even for the reads that were actually executed.

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>
