jtag_add_dr/ir_scan() now takes the tap as the first
argument, rather than for each of the fields passed
in.
The code never exercised the path where there was
more than one tap being scanned, who knows if it even
worked.
This simplifies the implementation and reduces clutter
in the calling code.
use jtag_add_ir/dr_plain_scan() for more fancy situations.

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.

Rename some (mostly) generic ARM functions:
armv4_5_arch_state() --> arm_arch_state()
armv4_5_get_gdb_reg_list() --> arm_get_gdb_reg_list()
armv4_5_init_arch_info() --> arm_init_arch_info()
Cores using the microcontroller profile may want a different
arch_state() routine though.
(Also fix strange indentation in arm_arch_state: use tabs only!
And update a call to it, removing assignment-in-conditional.)

Move the ARM opcode macros from <target/armv4_5.h>, and a few
Thumb2 ones from <target/armv7m.h>, to more appropriate homes
in a new <target/arm_opcodes.h> file.
Removed duplicate opcodes from that v7m/Thumb2 set. Protected
a few macro argument references by adding missing parentheses.
Tightening up some of the line lengths turned up a curious artifact:
the macros for the Thumb opcodes are all 32 bits wide, not 16 bits.
There's currently no explanation for why it's done that way...

Uses chaining of command_registration structures to eliminate all
target_type register_callback routines. Exports the command_handler
registration arrays for those target types that are used by others.
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.

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.

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.

The quit entry point was not being invoked. Just a source
of confusion at this point. XScale ran 100x reset upon
quit, but that code made no sense, wasn't commented
and never invoke.

The wrong variable (pc instead of r0) was used. Furthermore, someone
did cover this error by stupidly silencing the compiler warning that
occurred before a dummy void reference to r0 was added to the code.

this fn has something to do with the queue, which it does not as such.

- Move definition of 'struct target_type_s' into new 'target_type.h' file.
- Forward delclaration remains in target.h, with comment pointing to new file.
- Replaces #define with #include in source files.
git-svn-id: svn://svn.berlios.de/openocd/trunk@1971 b42882b7-edfa-0310-969c-e2dbd0fdcd60
- Add DEFINE_TARGET_TYPE_S symbol in files that need it defined.
- Forward declare 'struct target_type_s' only, unless that symbol is defined.
git-svn-id: svn://svn.berlios.de/openocd/trunk@1969 b42882b7-edfa-0310-969c-e2dbd0fdcd60
- replaces all calls to target->type->write_memory.
- add documentation in target_s to warn not to invoke callback directly.
