Spencer Oliver 1c975fe30b cortex_m: target implementation renames cortex_m3 to cortex_m
We changed the actual target name quite a while ago.
This changes the actual target function names/defines to also match
this change.

Hsiangkai Wang d979d78e97 gdb_server: support gdb target description
* 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;
};

calls could behave differently on an SWJ-DP instead of a SW-DP or

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.

David Brownell ce1feaa732 ARMv7-M: start using "struct arm"
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.

There are

 - And also some commands that valid at *any* time.

Update the docs to note that "help" now shows this mode info.

This also highlighted a few mistakes in command configuration,
mostly commands listed as "valid at any time" which shouldn't
