2009-11-23arm926ejs: retire cp15 commands, handled by mrc/mcr.Øyvind Harboe
Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
2009-11-22arm926ejs: fix warningsØyvind Harboe
buf_set_u32() operated on an uninitialized stack variable with non-byte boundaries, which led to warnings about reading uninitialized stack. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
2009-11-22ARM: remove 'armv4_5_common_s' migration #defineDavid Brownell
Finish migrating from the old symbol to the new one. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
2009-11-22ARM: arm_set_cpsr() handles T and J bitsDavid Brownell
Have arm_set_cpsr() handle the two core state flags, updating the CPU state. This eliminates code in various debug_entry() paths, and marginally improves handling of the J bit. Catch and comment a few holes in the handling of the J bit on ARM926ejs cores ... it's unlikely our users will care about Jazelle mode, but we can at least warn of Impending Doom. If anyone does use it, these breadcrumbs may help them to find the right path through the code. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
2009-11-22ARM: define two register utilitiesDavid Brownell
Define arm_reg_current() ... returning handle to a given register, and encapsulating the current mode's register shadowing. It's got one current use, for reporting the current register set to GDB. This will let later patches clean up much ARMV4_5_CORE_REG_MODE() nastiness, saving a bit of code. Define and use arm_set_cpsr() ... initially it updates the cached CPSR and sets up state used by arm_reg_current(), plus any SPSR handle. (Later: can also set up for T and J bits.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
2009-11-22ARM: simplify CPSR handlingDavid Brownell
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>
2009-11-17ARM: add arm_mode_name()David Brownell
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>
2009-11-17command_handler: change 'cmd_ctx' to CMD_CTXZachary T Welch
Convert all command handler 'cmd_ctx' parameter usage with CMD_CTX.
2009-11-17command_handler: change 'args' to CMD_ARGVZachary T Welch
This patch converts all instances of 'args' in COMMAND_HANDLER routines to use CMD_ARGV macro.
2009-11-17command_handler: change to 'argc' to CMD_ARGCZachary T Welch
This patch converts all instances of 'argc' in COMMAND_HANDLER routines to use CMD_ARGC.
2009-11-17ARM9TDMI: remove now-needless "struct arm9tdmi"David Brownell
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>
2009-11-16target: no implicit #includes of "register.h"David Brownell
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>
2009-11-15ARM: memory utils aren't ARM7/ARM9 dependentDavid Brownell
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>
2009-11-13ARM7/ARM9: use shared examine() methodDavid Brownell
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>

2009-11-13scan_field_t -> struct scan_fieldZachary T Welch
Remove useless structure typedef.
2009-11-13jtag_tap_t -> struct jtag_tapZachary T Welch
Search and destroy the jtag_tap_t typedef. This also cleans up a layering violation, removing the declaration from types.h.
2009-11-13add CMD_NAME macro for command handlersZachary T Welch
By introducing the CMD_NAME macro, this parameter may be integrated as args[-1] in command.[ch], without touching any other call sites.
2009-11-13use COMMAND_HANDLER macro to define all commandsZachary T Welch
2009-11-05ARM926 uses the new inheritance/nesting schemeDavid Brownell
Use target_to_arm926(), replacing needless pointer traversals and simplifying a bunch of code. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
2009-11-05ARM926: more cleanupDavid Brownell
An init_target() wrapper isn't needed, and target_create() can shrink a bit. Add a header comment and some doxygen. Remove arm926ejs_catch_broken_irscan() which has been a NOP for quite a few months now, and in any case duplicates logic in the JTAG core to validate IR capture data. But force the capture mask to 0x0f, so those tests are most effective. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
2009-11-05Improve arm926ejs command argument parsing.Zachary T Welch
2009-11-05target: remove unused interface fn that clutters codeØyvind Harboe
The quit entry point was not being invoked. Just a source of confusion at this point. XScale ran 100x reset upon quit, but that code made no sense, wasn't commented and never invoke. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
2009-10-30ARM926: fix arm926ejs_mmu() reading from bad pointerDavid Brownell
I'm suspecting this code can never have worked, since the original commit (svn #335) in early 2008. Fix is just copy/paste from another (working) function. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
2009-10-28ARM926: remove exports and forward declsDavid Brownell
Unneeded exports cause confusion about the module interfaces. Only the Feroceon code builds on this, so only routines it reuses should be public.. Make most remaining functions static, and fix some of the line-too-long issues. The forward decls are just code clutter; move their references later, after the normal declarations. Turns out we don't need even one forward declaration in this file. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

2009-10-05Minor cleanup to ARM926 debug entry:dbrownell
- don't needlessly export this function - handle "case 0" debug method-of-entry better (silent by default) The "case 0" is a valid debug entry mode so it doesn't deserve the warning int now gets. But it probably means that OpenOCD confused itself somehow; or that it confused the ARM9EJS target. git-svn-id: svn://svn.berlios.de/openocd/trunk@2799 b42882b7-edfa-0310-969c-e2dbd0fdcd60
