* target: simplify register get/set opsDavid Brownell2009-11-1713-127/+60
| | | | | | | | | | | No need to indirect from registered integers to pointers. Just stash the pointers directly in the register struct, and don't even bother registering. This is a small code shrink, speeds register access just a smidgeon, and gets rid of another rude exit() path. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM9TDMI: remove now-needless "struct arm9tdmi"David Brownell2009-11-179-72/+45
| | | | | | | And move the rest of the vector_catch stuff into the C file; it's not part of the module interface. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM7TDMI: remove now-needless "struct arm7tdmi"David Brownell2009-11-174-29/+21

* ARMv7-A: no exit() callsDavid Brownell2009-11-162-4/+3
| | | | | | | Also, switch integrity check over to the correct magic number, and remove duplicate v4/v5 #define. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* Cortex-A8: no exit() calls, add missing v7-A initDavid Brownell2009-11-161-31/+16
| | | | | | | Eventually there should be a v7a init routine, but for now all that is inlined here. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* Cortex-M3: don't exit()David Brownell2009-11-161-24/+10
| | | | | | | Get rid of undesirable and needless exit() calls from the Cortex-M3 support. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARMv7A: use standard disassemblerDavid Brownell2009-11-161-83/+0
| | | | | | We no longer need v7A-specific code for this. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: register (most) standard ARM commandsDavid Brownell2009-11-162-1/+10
| | | | | | | Have ARM11 register the "standard" ARM commands. For now, only disassembly really works. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: "armv4_5" command prefix becomes "arm"David Brownell2009-11-161-9/+9
| | | | | | | | | | Rename the "armv4_5" command prefix to straight "arm" so it makes more sense for newer cores. Add a simple compatibility script. Make sure all the commands give the same "not an ARM" diagnostic message (and fail properly) when called against non-ARM targets. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* fileio: improve API typesZachary T Welch2009-11-165-15/+15
| | | | | | | | | | | | | Use size_t instead of uint32_t when specifying file sizes. Update all consumers up through the layers to use size_t when required. These changes should be safe, but the higher-levels will need to be updated further to receive the intended benefits (i.e. large file support). Add error checking for fileio_read and file_write. Previously, all errors were being silently ignored, so this change might cause some problems for some people in some cases. However, it gives us the chance to handle any errors that do occur at higher-levels, rather than burying our heads in the sand.
* struct fileio: improve member typesZachary T Welch2009-11-161-1/+1
| | | | | | Add const keyword to file url and cast to free(). Make size an ssize_t and chase all format strings that use it.
* ARM: standard disassembler uses Thumb2 entryDavid Brownell2009-11-162-38/+38
| | | | | | | | | | | | | | | | | Tweak "standard" ARM disassembler diagnostics to fail if the target is not "an ARM" (vs. not "an ARMV4/5"), so it makes more sense for cores inheriting this as the "generic" disassembler. Also, to use the Thumb2 entry instead of the original Thumb entry. This makes it work better for both newer cores (which support those added instructions) and for BL and BLX instructions on older cores. (Those instructions are 32-bits, which requires curious state-aware code to go through a 16-bit decode interface...) Plus minor cleanups, notably to have fewer exit paths and to make sure they all return failure codes. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target: don't include "log.h" from "armv4_5.h"David Brownell2009-11-162-1/+1
| | | | | | | No point in multiple includes, and that file doesn't use its functions any more. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: move mode functions out of headerDavid Brownell2009-11-162-40/+56
| | | | | | | | | They're really too big to inline, at least for code that's not in any performance-critical loops. Also move the associated string table to the rodata section. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target: less implicit inclusion of "etm.h"David Brownell2009-11-169-2/+13
| | | | | | | 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 Welch2009-11-168-44/+32
| | | | | | | | 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).
* armv7m: make core reg read/write use unsignedZachary T Welch2009-11-162-6/+6
| | | | | | Eliminate redundant check that gets covered by using unsigned type. Created to eliminate noise from subsequent patches, but this kind of conversion will be beneficial in similar ways throughout the tree.
* rename CEIL as DIV_ROUND_UPZachary T Welch2009-11-164-8/+8
| | | | | Improves the name of this macro, moves it to types.h, and adds a block of Doxygen comments to describe what it does.
* move container_of to types.hZachary T Welch2009-11-161-13/+0
| | | | | | The container_of macro is useful as a general solution. It belongs in types.h, rather than target.h where it was introduced. Requires the offsetof macro, which comes from <stddef.h> (moved as well).
* #include "target.h" less wildlyDavid Brownell2009-11-169-6/+7
| | | | | | | | | Don't include "target.h" from more headers than necessary. This avoids needless interdependencies and duplicated include paths. Don't needlessly include it in source files, either. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target: no implicit #includes of "register.h"David Brownell2009-11-1627-10/+21
| | | | | | | | | | | | 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. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target: less implicit inclusion of "command.h"David Brownell2009-11-165-7/+3
| | | | | | | | | | Lots of files still include it, often through needless duplicate inclusion of "log.h"; sigh. This cleans up the inclusion graph a bunch, so there are fewer inclusion paths, but it doesn't change much otherwise. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target: don't implicitly include "algorithm.h"David Brownell2009-11-166-3/+6
| | | | | | | | | | | | | | Most files in the tree seem to have ended up including this, and *quite* needlessly ... only code implementing or using downloadable algorithms 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. Also: "algorithm.h" doesn't need to include "types.h" again; it already comes from a different header. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target: don't implicitly include "breakpoint.h"David Brownell2009-11-1611-2/+11
| | | | | | | | | | | 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>
* ARM11: use now-generic memory utilsDavid Brownell2009-11-151-11/+2
| | | | | | | | | | | | Now the ARM11 cores can use the renamed arm_checksum_memory() and arm_blank_check_memory() routines ... do so. Sanity checked with "flash erase_check" of both NOR banks on an OMAP2420 ... the algorithm code dumped four lines of of "poll" status after each of almost 520 blocks (yes, *very* annoying) but gave plausible results after producing that spam. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: fixup method tableDavid Brownell2009-11-152-47/+43
| | | | | | | | | 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>
* ARM: memory utils aren't ARM7/ARM9 dependentDavid Brownell2009-11-1515-178/+209
| | | | | | | | | | | | | | | | The arm7_9_checksum_memory() and arm7_9_blank_check_memory() routines are not actually specific to the ARM7 and ARM9 core generations ... they can work for any core which can run algorithms using basic ARM (not Thumb) instructions. Rename them; move the declarations to a more generic site; likewise move the code (and tidy it a bit in the process). NOTE: the blank_check() method falsely returned a success status (0) on one error path, when the algorithm failed. Fixed this bug. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target: make "examined" flag be per-targetDavid Brownell2009-11-155-44/+53
| | | | | | | | | | | | | | | | | | Previously this flag was stored in "target_type", so that for example if there were two ARM7TDMI targets in a scan chain, both would claim to have been examined although only the first one actually had its examine() method called. Move this state to where it should have been in the first place, and hide a method that didn't need exposure ... the flag is write-once. Provide some doxygen. The examine() method is confusing, since it isn't separating one-time setup from the after-each-reset stuff. And the ARM7/ARM9 version is, somewhat undesirably, not leaving the debug state alone after reset ... probably more of an issue for trace setup than for watchpoints and breakpoints.

* remove unused arm_jtag_buf_to_* helpersZachary T Welch2009-11-142-106/+0
| | | | | | Removes unused arm_jtag_buf_* helpers from arm_jtag.[ch]. These could reappear if patches are provided to conver the tree to use them, but this code should not be in the master tree until that series is ready.
* struct scan_field_s -> struct scan_fieldZachary T Welch2009-11-142-24/+24
| | | | | Remove obsolete suffix from struct scan_field. Somehow, these definitions did not get updated but did not cause any errors.
* Fix for md* commands, similar to mw*.Krzysztof Dziuba2009-11-141-1/+2
|
* Invalid command syntax errors with MWW.Dean Glazeski2009-11-141-1/+2
| | | | | This fixes an issue due to the new command handler syntax caused by the mw handler playing with the args pointer before using the CMD_NAME macro. Fix is to move this call above the lines changing args.
* compile with cygwin (32-bit)Ferdinand Postema2009-11-143-16/+25
| | | | | | | | Changed some printf format strings.. [dbrownell@users.sourceforge.net: shrink lines, fix indents] Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: ETM + ETB supportDavid Brownell2009-11-131-1/+15
| | | | | | | | | | | Kick in ETM (and ETB) support for ARM11. Tested on OMAP 2420, so update that configuration. (That's an ARM1136ejs, ETB, OpenGL ES1.1, C55x DSP, etc.) Also update the other ARM11 ETM + ETB targets in the tree to set up these modules. (Not tested.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: revert etmr/etmw commandsDavid Brownell2009-11-133-165/+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>
* ARM7/ARM9: use shared examine() methodDavid Brownell2009-11-1312-84/+65
| | | | | | | | | No point in having two identical examine methods for the ARM7TDMI and ARM9TDMI drivers; move, rename, shrink, share. Add a bit of doxygen; stop needlessly exporting a method. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ETM: simplify ETM initialization code pathsDavid Brownell2009-11-133-18/+14
| | | | | | | | | Return NULL from etm_build_reg_cache() not ERROR_OK; and share code on that fault path. Let ETM code handle any tracking of its cache -- not callers. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: switch to new "arm" base typeDavid Brownell2009-11-133-35/+39
| | | | | | | | | | 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>
* target: remove unused "bitfield" infrastructureDavid Brownell2009-11-139-73/+78
| | | | | | | | | | | | | | We have too many different registers, and too many version and context dependent interpretations, for this type of bitfield management to be scalable. (Anyone who really wants bitfield interpretation *can* do that in Tcl code...) There are ... quite a few copies of the same ARM dummy registers. There should eventually be one copy; this many is craziness. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM7/9: rm arm7_9_get_arch_pointers()David Brownell2009-11-132-64/+29
| | | | | | | | | | Remove the last external user of arm7_9_get_arch_pointers(), and that annoying downcast utility. Add an is_arm7_9() predicate. Stop returning specious success codes on various failure paths in the ARM7/ARM9 commands which used that downcast utility. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* command_t -> struct commandZachary T Welch2009-11-1319-20/+20
| | | | Remove misleading typedef and redundant suffix from struct command.
* command_context_t -> struct command_contextZachary T Welch2009-11-1345-96/+96
| | | | Remove misleading typedef and redundant suffix from struct command_context.
* target_t -> struct targetZachary T Welch2009-11-1360-972/+970
| | | | Remove misleading typedef and redundant suffix from struct target.
* reg_t -> struct regZachary T Welch2009-11-1327-152/+152
| | | | Remove misleading typedef and redundant suffix from struct reg.
