* ARM: remove per-register mallocDavid Brownell2009-11-191-0/+1
| | | | | | | Just pre-allocate memory for the cached register value. Shrinks heap overhead; increases locality-of-reference. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARMv7-A: use standard ARM core statesDavid Brownell2009-11-191-0/+1
| | | | | | | | | | | | | | | We don't want an ARMv7-specific core state enumeration just to add ThumbEE state. Update the generic stuff to handle that, and replace the V7-specific bits with it. For Cortex-A8: on debug entry, check both the T and J bits instead of just the T bit. When the J bit is set, set the right state and warn appropriately. (And while we're at it, move the generic arm struct to the front of the v7a structure, for somewhat better code generation.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: setup "secure monitor mode" shadow regsDavid Brownell2009-11-181-2/+3
| | | | | | | | | | | | | Teach the "armv4_5" register code to understand about the secure monitor mode: - Add the other three shadowed registers to the arrays - Support another internal mode number (sigh) in mappings - Catch malloc/calloc failures building that register cache This should kick in for Cortex-A8 and ARM1176. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: add "core_type" field to "struct arm"David Brownell2009-11-181-1/+9
| | | | | | | | | | It's used to flag cores with the "TrustZone" extension, and is used in subsequent patches to set up support for the registers shadowed by its new secure monitor mode. The ARM1176 and Cortex-A8 both support this new mode. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: add is_arm_mode()David Brownell2009-11-171-3/+3
| | | | | | | | | | | | | | | | | | Add a new is_arm_mode() predicate, and use it to replace almost all calls to current armv4_5_mode_to_number(). Eventually those internal mode numbers should vanish... along with their siblings in the armv7a.c file. Remove a handful of superfluous checks ... e.g. the mode number was just initialized, or (debug entry methods) already validated. Move one of the macros using internal mode numbers into the only file which uses that macro. Make the tables manipulated with those numbers be read-only and, where possible, static so they're not confused with part of the generic ARM interface.

* ARM: add arm_mode_name()David Brownell2009-11-171-2/+2
| | | | | | | | | | | | | | | Add and use arm_mode_name() to map from PSR bits to user meaningful names. It uses a new table which, later, can be used to hold other mode-coupled data. Add definitions for the "Secure Monitor" mode, as seen on some ARM11 cores (like ARM1176) and on Cortex-A8. The previous mode name scheme didn't understand that mode. Remove the old mechanism ... there were two copies, caused by Cortex-A8 needing to add "Secure Monitor" mode support. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: only use one set of dummy FPA registersDavid Brownell2009-11-171-0/+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.)

* target: don't include "log.h" from "armv4_5.h"David Brownell2009-11-161-1/+0
| | | | | | | 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 Brownell2009-11-161-38/+4
| | | | | | | | | 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 Brownell2009-11-161-1/+1
| | | | | | | 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>
* target: no implicit #includes of "register.h"David Brownell2009-11-161-1/+0
| | | | | | | | | | | | 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 Brownell2009-11-161-1/+0
| | | | | | | | | | 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>
* ARM: memory utils aren't ARM7/ARM9 dependentDavid Brownell2009-11-151-3/+6
| | | | | | | | | | | | | | | | 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>

* ETM: remove old mid-level ETM handleDavid Brownell2009-11-111-0/+1
| | | | | | | | | | | | | | | | | | Now that nothing uses the old ETM handle any more, remove it. Add minimal header tweaks, letting non-ARM7 and non-ARM9 cores access ETM facilities. Now ARM11 could support standard ETM (and ETB) access as soon as it derives from "struct arm" ... its scanchain 6 is used access the ETM, just like ARM7 and ARM9. The Cortex parts (both M3 and A8) will need modified access methods (via ETM init parameters), so they use the DAP. Our first A8 target (OMAP3) needs that for both ETM and ETB, but the M3 ETM isn't very useful without SWO trace support (it's painfully stripped down), so that support won't be worth adding for a while.

* ARM: start generalized base typeDavid Brownell2009-11-111-5/+31
| | | | | | | | | | | | | | | | Rename "struct armv4_5_common_s" as "struct arm". It needs a bit more work to be properly generic, and to move out of this header, but it's the best start we have on that today. Add and initialize an optional ETM pointer, since that will be the first thing that gets generalized. The intent being: all ARMs should eventually derive from this "struct arm", so they can reuse the current ETM logic. (And later, more.) Currently the ARM cores that *don't* so derive are only ARMv7-M (and thus Cortex-M3) and ARM11. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* src/target: remove 'extern' and wrap headersZachary T Welch2009-11-091-7/+13
| | | | Remove extern keywords from function prototypes and wrap long lines.
* target: provide container_of()David Brownell2009-11-051-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | Provide a cleaner way to handle single inheritance of targets in C, using the same model Linux does: structs containing other structs, un-nested via calls to a "container_of()" macro that are packaged in typesafe inline functions. Targets already use this containment idiom, but make it much more complicated because they un-nest using embedded "void *" pointers ... in chains of up to five per target, which is all pure needless complication. (Example: arm92x core, arm9tdmi, arm7_9, armv4_5 ... on top of the base "target" class.) Applying this scheme consistently simplifies things, and gets rid of many error-prone untyped pointers. It won't change any part of the type model though -- it just simplifies things. (And facilitates more cleanup later on.) Rule of thumb: where there's an X->arch_info void* pointer, access to that pointer can and should be removed. It may be convenient to set up pointers to some of the embedded structs; and shrink their current "*_common" names (annoyingly long). Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* David Brownell <david-b@pacbell.net> oharboe2009-09-091-0/+1
| | | | | | | | | | | | | | | | | Optionally shave time off the armv4_5 run_algorithm() code: let them terminate using software breakpoints, avoiding roundtrips to manage hardware ones. Enable this by using BKPT to terminate execution instead of "branch to here" loops. Then pass zero as the exit address, except when running on an ARMv4 core. ARM7TDMI, ARM9TDMI, and derived cores now set a flag saying they're ARMv4. Use that mechanism in arm_nandwrite(), for about 3% speedup on a DaVinci ARM926 core; not huge, but it helps. Some other algorithms could use this too (mostly flavors of flash operation). git-svn-id: svn://svn.berlios.de/openocd/trunk@2680 b42882b7-edfa-0310-969c-e2dbd0fdcd60
