* ARM11: remove disabled register hooksDavid Brownell2009-11-221-88/+1
| | | | | | | | Minor cleanup of ARM11 register handling: remove disabled register hooks. This should all be handled by shared code, and this stuff is just clutter. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* add handle_command_parse_bool command helperZachary T Welch2009-11-181-45/+10
| | | | | | | | | Rewrite arm11_handle_bool to provide a generic on/off command helper. Refactors COMMAND_PARSE_BOOL to use new command_parse_bool helper, which gets reused by the new command_parse_bool_any helper. This later helper is called by the new command helper function to accepts any on/off, enable/disable, true/false, yes/no, or 0/1 parameter.
* ARM: add "core_type" field to "struct arm"David Brownell2009-11-181-4/+17
| | | | | | | | | | 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 Brownell2009-11-171-1/+1
| | | | | | | | | | | | | | | | | | 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: only use one set of dummy FPA registersDavid Brownell2009-11-171-38/+3
| | | | | | | | | | | | | | | | 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.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* 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 Welch2009-11-171-3/+3
| | | | | This patch converts all instances of 'argc' in COMMAND_HANDLER routines to use CMD_ARGC.
* target: simplify register get/set opsDavid Brownell2009-11-171-8/+6
| | | | | | | | | | | 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>
* target: remove some more duplicate includesDavid Brownell2009-11-171-1/+0
| | | | Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: fewer exit() callsDavid Brownell2009-11-161-4/+6
| | | | Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: register (most) standard ARM commandsDavid Brownell2009-11-161-0/+2
| | | | | | | Have ARM11 register the "standard" ARM commands. For now, only disassembly really works. 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>
* move ARRAY_SIZE macro to types.hZachary T Welch2009-11-161-9/+9
| | | | | | | | 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).
* 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>
* ARM11: use now-generic memory utilsDavid Brownell2009-11-151-11/+2
| | | | | | | | | | | | Now the ARM11 cores can use the renamed arm_checksum_memory() and arm_blank_check_memory() routines ... do so. Sanity checked with "flash erase_check" of both NOR banks on an OMAP2420 ... the algorithm code dumped four lines of of "poll" status after each of almost 520 blocks (yes, *very* annoying) but gave plausible results after producing that spam. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: fixup method tableDavid Brownell2009-11-151-45/+43
| | | | | | | | | Three changes: remove ARM11_HANDLER() in favor of normal structure initialization syntax; fix goofy indentation in that structure; and don't needlessly export arm11_register_commands(), it's only called through that method table. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target: make "examined" flag be per-targetDavid Brownell2009-11-151-6/+0
| | | | | | | | | | | | | | | | | | Previously this flag was stored in "target_type", so that for example if there were two ARM7TDMI targets in a scan chain, both would claim to have been examined although only the first one actually had its examine() method called. Move this state to where it should have been in the first place, and hide a method that didn't need exposure ... the flag is write-once. Provide some doxygen. The examine() method is confusing, since it isn't separating one-time setup from the after-each-reset stuff. And the ARM7/ARM9 version is, somewhat undesirably, not leaving the debug state alone after reset ... probably more of an issue for trace setup than for watchpoints and breakpoints. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: ETM + ETB supportDavid Brownell2009-11-131-1/+15
| | | | | | | | | | | Kick in ETM (and ETB) support for ARM11. Tested on OMAP 2420, so update that configuration. (That's an ARM1136ejs, ETB, OpenGL ES1.1, C55x DSP, etc.) Also update the other ARM11 ETM + ETB targets in the tree to set up these modules. (Not tested.) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: revert etmr/etmw commandsDavid Brownell2009-11-131-83/+0
| | | | | | | These aren't desirable, given "standard" ETM support. Also remove the now-unused arm11_find_target(). Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM11: switch to new "arm" base typeDavid Brownell2009-11-131-32/+28
| | | | | | | | | | This will enable reusing many common ARM utilities, in particular the ETM and ETB support. The ARM11 support can still be much simplified after this patch, though. Note: none of those common utilities kick in yet... Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target: remove unused "bitfield" infrastructureDavid Brownell2009-11-131-6/+21
| | | | | | | | | | | | | | 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>

* jtag_tap_t -> struct jtag_tapZachary T Welch2009-11-131-1/+1
| | | | | Search and destroy the jtag_tap_t typedef. This also cleans up a layering violation, removing the declaration from types.h.
* use CALL_COMMAND_HANDLER instead of direct callsZachary T Welch2009-11-131-3/+4
| | | | | | By using CALL_COMMAND_HANDLER, parameters can be reordered, added, or even removed in inherited signatures, without requiring revisiting all of the various call sites.
