* ARM: arm_set_cpsr() handles T and J bitsDavid Brownell2009-11-221-11/+21
| | | | | | | | | | | | | | 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>
* ARM: define two register utilitiesDavid Brownell2009-11-221-10/+8
| | | | | | | | | | | | | | 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.)

* ARM: simplify CPSR handlingDavid Brownell2009-11-221-22/+37
| | | | | | | | | | | | | | 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>
* ARM: pass 'struct reg *' to register r/w routinesDavid Brownell2009-11-201-24/+18
| | | | | | | | | | | | | | | | Implementations need to access the register struct they modify; make it easier and less error-prone to identify the instance. (This removes over 10% of the ARMV4_5_CORE_REG_MODE nastiness...) Plus some minor fixes noted when making these updates: ARM7/ARM9 accessor methods should be static; don't leave CPSR wrongly marked "dirty"; note significant XScale omissions in register handling; and have armv4_5_build_reg_cache() record its result. Rename "struct armv4_5_core_reg" as "struct arm_reg"; it's used for more than those older architecture generations. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM7/ARM9: remove old "debug commands"David Brownell2009-11-201-130/+0
| | | | | | | | | | | | | | | Remove two commands that were documented as "debug commands" and where "you probably don't want to use this". We never intended to support them, and at least one problem report boiled down to using this when it shouldn't have been used. Update the docs on the existing register commands to talk a bit more about register access and cache behavior. (Those debug commands existed largely to *bypass* the cache.) And fix some minor doc goofs that snuck in with recent changes, renaming "armv4_5" as "arm" and "arm9tdmi" as "arm9". Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target: create/use register_cache_invalidate()David Brownell2009-11-191-7/+4
| | | | | | | | | | | | | | | 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>
* remove fast command and jim_global_longZachary T Welch2009-11-181-2/+2
| | | | | | | | Removing the fast command eliminates the fast_and_dangerous global, which was used only by arm7_9_common as an initializer. The command is not called in the tree; instead, more explicit commands are used. The jim_global_long function was not used anywhere in the tree.
* use COMMAND_PARSE_ENABLE macro where appropriateZachary T Welch2009-11-181-42/+3
| | | | | | | | Updates all command parsing of simple "enable" and "disable" arguments. A few case in the tree use a tri-state or extended arguments, which cannot use this simple macro. Simlifies the xscale icache/dcache command handler logic.
* ARM: add is_arm_mode()David Brownell2009-11-171-16/+7
| | | | | | | | | | | | | | | | | | 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 Brownell2009-11-171-3/+8
| | | | | | | | | | | | | | | 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>
* command_handler: change 'cmd_ctx' to CMD_CTXZachary T Welch2009-11-171-24/+24

* command_handler: change 'args' to CMD_ARGVZachary T Welch2009-11-171-14/+14
| | | | | 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 Welch2009-11-171-6/+6
| | | | | This patch converts all instances of 'argc' in COMMAND_HANDLER routines to use CMD_ARGC.

* target: less implicit inclusion of "etm.h"David Brownell2009-11-161-0/+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 Brownell2009-11-161-0/+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>
* ARM: memory utils aren't ARM7/ARM9 dependentDavid Brownell2009-11-151-150/+0
| | | | | | | | | | | | | | | | 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>
* ARM7/ARM9: use shared examine() methodDavid Brownell2009-11-131-2/+56
| | | | | | | | | 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>
* ARM7/9: rm arm7_9_get_arch_pointers()David Brownell2009-11-131-63/+24
| | | | | | | | | | 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>

* finish removing deprecated/obsolete commandsDavid Brownell2009-11-091-1/+0
| | | | | | | | | | | | | | | | | | | | It's been about a year since these were deprecated and, in most cases, removed. There's no point in carrying that documentation, or backwards compatibility for "jtag_device" and "jtag_speed", around forever. (Or a few remnants of obsolete code...) Removed a few obsolete uses of "jtag_speed": - The Calao stuff hasn't worked since July 2008. (Those Atmel targets need to work with a 32KHz core clock after reset until board-specific init-reset code sets up the PLL and enables a faster JTAg clock.) - Parport speed controls don't actually work (tops out at about 1 MHz on typical HW). - In general, speed controls need to live in board.cfg files (or sometimes target.cfg files), not interface.cfg ...
