* ARM: simplify CPSR handlingDavid Brownell2009-11-221-10/+0
| | | | | | | | | | | | | | Stash a pointer to the CPSR in the "struct arm", to help get rid of the (common) references to its index in the register cache. This removes almost all references to CPSR offsets outside of the toplevel ARM code ... except a pair related to the current ARM11 "simulator" logic (which should be removable soonish). This is a net minor code shrink of a few hundred bytes of object code, and also makes the code more readable. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARMv7-A: use standard ARM core statesDavid Brownell2009-11-191-12/+2
| | | | | | | | | | | | | | | 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>
* ARMv7-A: use standard ARM core_mode symbolsDavid Brownell2009-11-191-15/+2
| | | | | | | | | The only way ARMv7-A modes differ from ARMv4/ARMv5 flavors is that v7-A is allowed to include "Secure monitor" support. That's now handled by our standard top-level ARM code ... so phase out the stuff that's specific to ARMv7-A. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM: simplify ARMv7-A register handlingDavid Brownell2009-11-181-52/+0
| | | | | | | | | | | | | | | | | | | ARMv7-A doesn't need to duplicate all the standard ARM code for register handling. - Switch Cortex-A8 to use the standard register code - Remove duplicated infrastructure from ARMv7-A - Have ARMv7-A arch_state() show CPSR, like other ARMs Add comments to show where the Cortex-A8 isn't actually doing the right thing for register reads/writes, unless core happens to be in the right mode to start with. (Looks like maybe there may be generic confusion between saved/current PSR values in all the ARM code ...) Make related ARMv7-A and Cortex-A8 symbols properly static.

* ARM: add arm_mode_name()David Brownell2009-11-171-2/+0
| | | | | | | | | | | | | | | 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>
* ARMv7-A: no exit() callsDavid Brownell2009-11-161-1/+0
| | | | | | | 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>
* #include "target.h" less wildlyDavid Brownell2009-11-161-1/+0
| | | | | | | | | 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 Brownell2009-11-161-1/+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>

* Cortex-A8: use the new inheritance/nesting schemeDavid Brownell2009-11-051-1/+0
| | | | | | | Use target_to_armv7a() etc, replacing needless pointer traversals. Stop using X->arch_info scheme in most ARMv7-A and Cortex-A8 code. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target: provide container_of()David Brownell2009-11-051-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | 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 Subset of Cortex-A8 support from Magnus: create an armv7a fileoharboe2009-08-251-0/+176
and seed it with DAP access support using the current ADIv5 code. (With tweaks and cleanup from Øyvind and Dave.) The ARMv7-AR architecture manual is not publicly available (even in subset form like the ARMv7-M spec), so it's hard to distinguish between the Cortex-A8 implementation and the ARMv7-A architecture. The register set presumably is architectural, and so it's stored here; it's like earlier ARMs, with small additions. Ditto the instruction set, though Thumb2 support is used (extending Thumb support from ARMv6 with more 32-bit instructions) and there's this ThumbEE thing too. There is a new "debug monitor" mode, not yet fully addressed here, to support debugging in environments (like motor control) where halting debug mode is inadvisable. git-svn-id: svn://svn.berlios.de/openocd/trunk@2608 b42882b7-edfa-0310-969c-e2dbd0fdcd60
