2014-04-14target: fix incorrect arm cpu monitor mode encodingTim Sander
According to the "Arm Arch Ref Manual ARMv7-a and ARMv7-R edition" the CPSR encoding for Monitor mode is 0b10110 (22) not 0b11010 (26) as is currently used.

2013-08-07gdb_server: support gdb target descriptionHsiangkai Wang
* Add a parameter in .get_gdb_reg_list() to return different register lists as generating target description. * Modify STRUCT REG to let gdb generate target description according to register information. The modified structure of register is struct reg { const char *name; uint32_t number; /* for regnum="num" */ struct reg_feature *feature; /* for register group feature name */ bool caller_save; /* for save-restore="yes|no" */ void *value; bool dirty; bool valid; bool exist; uint32_t size; struct reg_data_type *reg_data_type; /* for type="type" */ const char *group; /* for group="general|float|vector" */ void *arch_info; const struct reg_arch_type *type; }; Change-Id: I2096b67adf94518ba0b8b23d8c6a9f64ad7932b8 Signed-off-by: Hsiangkai Wang <hsiangkai@gmail.com> Reviewed-on: http://openocd.zylin.com/1382 Tested-by: jenkins Reviewed-by: Franck Jullien <franck.jullien@gmail.com> Reviewed-by: Spencer Oliver <spen@spen-soft.co.uk> Reviewed-by: Andreas Fritiofson <andreas.fritiofson@gmail.com>

To simplify things change over to using the generic core_mode struct rather than maintaining a armv7m specific one.

2012-08-29arm7_9: Fix broken halfword/byte memory readsAndreas Fritiofson
Always scan out all bits, but make sure only the allowed number of bytes end up in the caller-provided buffer. Discard the rest by adding another scan field when size < 4. Rewrite the endianness callback to avoid reading outside allocated memory. Make it directly usable as a callback without the need for a wrapper. Move the shared callback to a more suitable home in arm7_9_common. This fixes the regressions introduced in commits 991ed5a2b657e660f744eefddb084724e52938ea cb90d32e386a7489d31136997209c61e9559ff5e and c3074f377c1da33ca8ba8493826e1b52351eebc6 Change-Id: Ia8bde8c5a9844e89a1d6c0bc8534cd26f02f8d11 Signed-off-by: Andreas Fritiofson <andreas.fritiofson@gmail.com> Reviewed-on: http://openocd.zylin.com/789 Tested-by: jenkins Reviewed-by: Spencer Oliver <spen@spen-soft.co.uk> Reviewed-by: Freddie Chopin <freddie.chopin@gmail.com>

2011-11-14target: make it absolutely clear that no null pointers are acceptedØyvind Harboe
there are no comments about what the rules w.r.t. null pointers are and it is inconsistent. It's simply a bug in the app if we ask about the properties of a null pointer w.r.t. what kind of target it is. It's equally wrong to say that it is an arm target as that it isn't an arm target.

2010-03-05ADIv5 share DAP command supportDavid Brownell
Get rid of needless and undesirable code duplication for all the DAP commands (resolving a FIXME) ... there's no need for coreas to have private copies of that stuff. Stick a pointer to the DAP in "struct arm", letting common code get to it. Also rename the "swjdp_info" symbol; just call it "dap". This is an overall code shrink.

2010-02-21ARM: keep a handle to the PCDavid Brownell
Keep a handle to the PC in "struct arm", and use it. This register is used a fair amount, so this is a net minor code shrink (other than some line length fixes), but mostly it's to make things more readable. For XScale, fix a dodgy sequence while stepping. It was initializing a variable to a non-NULL value, then updating it to handle the step-over-active-breakpoint case, and then later testing for non-NULL to see if it should reverse that step-over-active logic. It should have done like ARM7/ARM9 does: init to NULL. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
2010-02-21ARMv7-M: start using "struct arm"David Brownell
This sets up a few of the core "struct arm" data structures so they can be used with ARMv7-M cores. Specifically, it: - defines new ARM core_modes to match the microcontroller modes (e.g. HANDLER not IRQ, and two types of thread mode); - Establishes a new microcontroller "core_type", which can be used to make sure v7-M (and v6-M) cores are handled right; - adds "struct arm" to "struct armv7m" and arranges for the target_to_armv7m() converter to use it; - sets up the arm.core_cache and arm.cpsr values - makes the Cortex-M3 code maintain arm.map and arm.core_mode. This is currently set up as a parallel data structure, primarily to minimize special cases for the semihosting support with microcontroller profile cores. Later patches can rip out the duplicative ARMv7-M support and start reusing core ARM code. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
2009-12-13target files shouldn't #include <target/...h>David Brownell
Make these ".h" files adopt the same policy the ".c" files already follow: don't use <subsystem/...h> syntax for private interfaces. If we ever get reviewed/supported "public" interfaces they should come exclusively from some include/... directory; that'll be the time to switch to <...> syntax for any subsystem's own interfaces.

2009-12-07ARM: use <target/arm.h> not armv4_5.hDavid Brownell
Move most declarations in <target/armv4_5.h> to <target/arm.h> and update users. What's left in the older file is stuff that I think should be removed ... the old register cache access stuff, which makes it awkward to support microcontroller profile (Cortex-M) cores. The armv4_5_run_algorithm() declaration was moved too, even though it's not yet as generic as it probably ought to be. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
