* Fix a bunch of typos.Uwe Hermann2011-03-171-1/+1
| | | | | | | | 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.
* warnings: use more 'const' for char *Øyvind Harboe2010-12-291-1/+1

* src: add loader src descriptionSpencer Oliver2010-10-281-0/+2
| | | | | | - add comment where to find the various loaders src files. Signed-off-by: Spencer Oliver <ntfreak@users.sourceforge.net>
* armv7m: exit_point optional for armv7m_run_algorithmSpencer Oliver2010-07-201-1/+1
| | | | | | | | | As the armv7m uses instruction breakpoints for algorithms we do not really need to check the pc on exit. This now matches the behaviour of the arm4_5 codebase. Signed-off-by: Spencer Oliver <ntfreak@users.sourceforge.net>
* armv7m: 20 second timeout/megabyte for CRC checkSpencer Oliver2010-05-101-1/+3
| | | | | | | There was a fixed 20 second timeout which is too little for large, slow timeout checks. Signed-off-by: Spencer Oliver <ntfreak@users.sourceforge.net>
* ARMv7M: review scope of functionsAntonio Borneo2010-04-101-1/+1
| | | | | | Add "static" qualifier to private functions. Signed-off-by: Antonio Borneo <borneo.antonio@gmail.com>
* arm7/9: remove unused post_restore_contextØyvind Harboe2010-03-171-3/+0
| | | | | | | Unused. If something should happen after context restore, then the calling code can just do it afterwards. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* ADIv5 share DAP command supportDavid Brownell2010-03-051-149/+1
| | | | | | | | | | | | | | Get rid of needless and undesirable code duplication for all the DAP commands (resolving a FIXME) ... there's no need for coreas to have private copies of that stuff. Stick a pointer to the DAP in "struct arm", letting common code get to it. Also rename the "swjdp_info" symbol; just call it "dap". This is an overall code shrink. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* rename "swjdp_common" as "adiv5_dap"David Brownell2010-03-041-5/+5
| | | | | | | | | | | | | This partially corrects an inappropriate name choice (and its associated FIXME). There are still too many variables named "swjdp", bug little current code actually relies on them referencing an SWJ-DP instead of some other flavor of DAP. Only the two new dap_to{swd,jtag}() calls could behave differently on an SWJ-DP instead of a SW-DP or a JTAG-DP. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* semihosting: add armv7m semihosting supportSpencer Oliver2010-02-281-2/+10
| | | | | | | do_semihosting and arm_semihosting now check the core type and use the generic arm structure. Signed-off-by: Spencer Oliver <ntfreak@users.sourceforge.net>
* ARMv7M: add arm cmd groupSpencer Oliver2010-02-281-0/+3
| | | | | | | | - Add arm cmd group to armv7m cmd chain. - arm cmd's now check the core type before running a cmd. - todo: add support for armv7m registers for reg cmd. Signed-off-by: Spencer Oliver <ntfreak@users.sourceforge.net>
* ARMv7M: use software breakpoints for algorithmsSpencer Oliver2010-02-281-18/+5
| | | | | | | | - armv7m_run_algorithm now requires all algorithms to use a software breakpoint at their exit address - updated all algorithms to support this Signed-off-by: Spencer Oliver <ntfreak@users.sourceforge.net>
* ARM: keep a handle to the PCDavid Brownell2010-02-211-3/+4
| | | | | | | | | | | | | | | | Keep a handle to the PC in "struct arm", and use it. This register is used a fair amount, so this is a net minor code shrink (other than some line length fixes), but mostly it's to make things more readable. For XScale, fix a dodgy sequence while stepping. It was initializing a variable to a non-NULL value, then updating it to handle the step-over-active-breakpoint case, and then later testing for non-NULL to see if it should reverse that step-over-active logic. It should have done like ARM7/ARM9 does: init to NULL. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARMv7-M: start using "struct arm"David Brownell2010-02-211-3/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | This sets up a few of the core "struct arm" data structures so they can be used with ARMv7-M cores. Specifically, it: - defines new ARM core_modes to match the microcontroller modes (e.g. HANDLER not IRQ, and two types of thread mode); - Establishes a new microcontroller "core_type", which can be used to make sure v7-M (and v6-M) cores are handled right; - adds "struct arm" to "struct armv7m" and arranges for the target_to_armv7m() converter to use it; - sets up the arm.core_cache and arm.cpsr values - makes the Cortex-M3 code maintain arm.map and arm.core_mode. This is currently set up as a parallel data structure, primarily to minimize special cases for the semihosting support with microcontroller profile cores. Later patches can rip out the duplicative ARMv7-M support and start reusing core ARM code. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARMv7-M: make DAP commands verify target is an ARMv7-MDavid Brownell2010-02-041-3/+26
| | | | | | | | Init the ARMv7-M magic number. Define predicate verifying it. Use it to resolve a lurking bug/FIXME: make sure the ARMv7-M specific DAP ops reject non-ARMv7-M targets. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARMv7-M: use command handler for "dap baseaddr".David Brownell2010-01-291-30/+1
| | | | | | | | | | Make the ARMv7-M DAP code reuse the command handler for "dap baseaddr". For some reason, this DAP command wasn't converted earlier. This is a code shrink and simplification; it also removes a needless transport dependency on JTAG. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARMV7M: handle bkpt instruction on resume/stepSpencer Oliver2010-01-201-0/+38
| | | | | | | | | | Skip over a bkpt instruction if found on resume/step. Only software breakpoints known to OpenOCD are currently handled. So this handles the special case of either a user added bkpt or library added, eg. semi-hosting support. Signed-off-by: Spencer Oliver <ntfreak@users.sourceforge.net>
* ARMv7: help/usage updatesDavid Brownell2010-01-071-13/+22
| | | | | | | | | | | | | | | | | | Provide helptext which was sometimes missing; update some of it to be more accurate. Usage syntax messages have the same EBNF as the User's Guide; there should be no angle brackets in either place. Don't use "&function"; functions are like arrays, their address is their name. Shrink some overlong lines, remove some empties. Add a couple comments about things that should change: those extra TCK cycles for MEM-AP reads are in the wrong place (that might explain some problems we've seen); the DAP command tables should be shared, not copied.

* ARMv7-M: use AP_REG_* symbolDavid Brownell2010-01-041-1/+6

* streamline and document helptext mode displaysDavid Brownell2010-01-021-1/+1
| | | | | | | | | | | | | | | | | | | Most commands are usable only at runtime; so don't bother saying that, it's noise. Moreover, tokens like EXEC are cryptic. Be more clear: highlight only the commands which may (also) be used during the config stage, thus matching the docs more closely. There are - Configuration commands (per documentation) - And also some commands that valid at *any* time. Update the docs to note that "help" now shows this mode info. This also highlighted a few mistakes in command configuration, mostly commands listed as "valid at any time" which shouldn't have been. This just fixes ones I noted when sanity testing.

* target: add debug_reason_name()David Brownell2009-12-071-2/+1
| | | | | | | | Provide and use debug_reason_name() instead of expecting targets to call Jim_Nvp_value2name_simple(). Less dependency on Jim, and the code becomes more clear too. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* use ARRAY_SIZE macroZachary T Welch2009-11-251-2/+2
| | | | | Search and destroy lingering cases where the ARRAY_SIZE macro should be used to convey more intrinsic meaning in the OpenOCD code.
* remove target_type register_command callbackZachary T Welch2009-11-241-6/+1
| | | | | | 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.
* armv7m: use register_commands()Zachary T Welch2009-11-241-28/+48
|
* use COMMAND_REGISTER macroZachary T Welch2009-11-241-6/+6
| | | | | Replaces direct calls to register_command() with a macro, to allow its parameters to be changed and callers updated in phases.
* target: create/use register_cache_invalidate()David Brownell2009-11-191-15/+0
| | | | | | | | | | | | | | | 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>
* ARM: only use one set of dummy FPA registersDavid Brownell2009-11-171-35/+2
| | | | | | | | | | | | | | | | All ARM cores need to provide obsolete FPA registers in their GDB register dumps. (Even though cores with floating point support now generally use some version of VFP...) Clean up that support a bit by sharing the same dummy registers, and removing the duplicate copies. Eventually we shouldn't need to export those dummies. (This makes the ARMv7-M support include the armv4_5 header, and cleans up related #includes, but doesn't yet use anything from there except those dummies.)

* command_handler: change 'cmd_ctx' to CMD_CTXZachary T Welch2009-11-171-7/+7
| | | | Convert all command handler 'cmd_ctx' parameter usage with CMD_CTX.
* command_handler: change 'args' to CMD_ARGVZachary T Welch2009-11-171-2/+2
| | | | | This patch converts all instances of 'args' in COMMAND_HANDLER routines to use CMD_ARGV macro.
* command_handler: change to 'argc' to CMD_ARGCZachary T Welch2009-11-171-2/+2
| | | | | This patch converts all instances of 'argc' in COMMAND_HANDLER routines to use CMD_ARGC.
* target: simplify register get/set opsDavid Brownell2009-11-171-11/+5
| | | | | | | | | | | 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>
* ARMv7-M: no exit() callsDavid Brownell2009-11-161-4/+4

* move ARRAY_SIZE macro to types.hZachary T Welch2009-11-161-9/+6
| | | | | | | | 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 Welch2009-11-161-4/+4
| | | | | | 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.
* #include "target.h" less wildlyDavid Brownell2009-11-161-0/+1
| | | | | | | | | 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 Brownell2009-11-161-0/+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. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target: don't implicitly include "algorithm.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 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 Brownell2009-11-161-0/+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>
* target: remove unused "bitfield" infrastructureDavid Brownell2009-11-131-9/+26
| | | | | | | | | | | | | | 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>
