* target: clean up target memory allocation error messagesØyvind Harboe2010-05-041-0/+8
| | | | | | | | | | target memory allocation can be implemented not to show bogus error messages. E.g. when trying a big allocation first and then a smaller one if that fails. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* TARGET: review unused symbolsAntonio Borneo2010-04-101-1/+0
| | | | | | | Remove unused functions: - target_all_handle_event Signed-off-by: Antonio Borneo <borneo.antonio@gmail.com>
* TARGET: review scope of functionsAntonio Borneo2010-04-101-15/+0
| | | | | | | Add "static" qualifier to private functions. Remove unused "extern" in src/ecosboard.c Signed-off-by: Antonio Borneo <borneo.antonio@gmail.com>
* target: are we running algorithm code?David Brownell2010-04-041-0/+8
| | | | | | | | | | | | | | | | | | | | | | Fixing one bug can easily uncover another .... in this case, making sure that we properly invalidate some cached NOR state when resuming arbitrary target code turned up an issue when the code wasn't quite arbitrary (and we couldn't know that, but some parts of OpenOCD assumed the cache would not be invalidated. Specifically: some flash drivers (like CFI) update that state in loops with downloaded algorithms, thus invalidating the state as it's probed. + Add a new target state flag, to record whether the target is running downloaded algorithm code. + Use that flag to add a special case: "trust" downloaded algorithms not to corrupt that cached state, bypassing cache invalidation. Also update some of the documentation to stipulate that this flavor of trustworthiness is now *required* ... not just a fortuitous acident.

* target: add todo in target_write_memory() about alignmentØyvind Harboe2010-02-091-2/+13
| | | | | | | target_write_buffer() does not align "buffer" in host memory passed to target_write_memory(). Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* target: add check_reset hookØyvind Harboe2010-01-131-1/+3
| | | | | | | Allow targets to run checks post reset. Used to check that e.g. DCC downloads have been enabled. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* target: further shrink Jim-awarenessDavid Brownell2009-12-131-2/+1
| | | | | | | | | | | | | Don't include <helper/jim.h> from target.h ... not everything which touches targets needs to be able to talk to Jim. Plus, most files include this header by another path. Also, switch the affected files to use the classic sequence for #included files: all <framework/headers.h> first, then the "local_headers.h". This helps prevent growth of problematic layering, by minimizing entanglement. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target: remove needless "extern"sDavid Brownell2009-12-081-10/+0
| | | | | | | | | | Most of these happened to be in the target.h file. Some of those are associated with symbols that could be removed at some point ... e.g. NVP_ASSERT/true and its sibling NVP_DEASSERT/false. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target: add debug_reason_name()David Brownell2009-12-071-2/+2
| | | | | | | | Provide and use debug_reason_name() instead of expecting targets to call Jim_Nvp_value2name_simple(). Less dependency on Jim, and the code becomes more clear too. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* change #include "types.h" to <helper/types.h>Zachary T Welch2009-12-031-1/+1
| | | | | | | | | | | | Changes from the flat namespace to heirarchical one. Instead of writing: #include "types.h" the following form should be used. #include <helper/types.h> The exception is from .c files in the same directory.
* change #include "jim.h" to <helper/jim.h>Zachary T Welch2009-12-031-1/+1

* do not extern 'interp' from command.cZachary T Welch2009-11-301-1/+0
| | | | | Adds 'interp' field to command_context, chasing the few remaining references to the global variable outside of the command module.
* target: avoid using interp global variableZachary T Welch2009-11-301-0/+1
| | | | | Adds 'interp' to target_event_action structure to avoid using the global variable of the same name.
* target: remove unused TARGET_EVENT_OLD_* symbolsDavid Brownell2009-11-281-2/+0
| | | | | | Just two *_OLD_* symbols left... Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target: groundwork for "reset-assert" eventDavid Brownell2009-11-271-1/+4
| | | | | | | | | This defines a "reset-assert" event and a supporting utility routine, and documents both how targets should implement it and how config scripts should use it. Core-specific updates are needed to make this work. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target: create and use target_name()David Brownell2009-11-251-0/+6
| | | | | | | | | | | | | Several of the sites now using target_type_name() really ought to be using an instance-specific name. Create a function called target_name(), accessing the instance's own (command) name. Use it in several places that really should be displaying instance-specific names. Also in several places which were already doing so, but which had no wrapper to call. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target: target_get_name() --> target_type_name()David Brownell2009-11-251-2/+3
| | | | | | | | | | | | | There are two names that may matter on a per-target basis. One is a per-instance name (for example, "at91sam7s.cpu"). The other is the name of its type (for example, "arm7tdmi"), which is shared among multiple targets. Currently target_get_name() returns the type name, which is misleading and is rarely appropriate for target diagnostics. Rename that as target_type_name(). Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* move container_of to types.hZachary T Welch2009-11-161-13/+0
| | | | | | The container_of macro is useful as a general solution. It belongs in types.h, rather than target.h where it was introduced. Requires the offsetof macro, which comes from <stddef.h> (moved as well).
* target: less implicit inclusion of "command.h"David Brownell2009-11-161-3/+3
| | | | | | | | | | 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>
* target: don't implicitly include "algorithm.h"David Brownell2009-11-161-1/+2
| | | | | | | | | | | | | | 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 Brownell2009-11-161-1/+2
| | | | | | | | | | | 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>
* target: make "examined" flag be per-targetDavid Brownell2009-11-151-8/+24
| | | | | | | | | | | | | | | | | | 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.

* target.h: remove extern keyword and wrapZachary T Welch2009-11-091-53/+72
| | | | Removes 'extern' keyword from function prototypes and wraps long lines.
* target: provide container_of()David Brownell2009-11-051-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | 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>
* target: require working area for physical/virtual addresses to be specifiedØyvind Harboe2009-11-031-3/+5
| | | | | | | | | | | | | | | | Fixed bug: if virtual address for working memory was not specified and MMU was enabled, then address 0 would be used. Require working address to be specified for both MMU enabled and disabled case. For some completely inexplicable reason this fixes the regression in svn 2646 for flash write in arm926ejs target. The logs showed that MMU was disabled in the case below: https://lists.berlios.de/pipermail/openocd-development/2009-November/011882.html Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
