Change [1] introduced a regression that results in comparison
in arm_jtag_set_instr() to be always true if the length of the
IR register is not 8 bit. The value on the left side
of the != operator contains only tap->ir_length number of
bits while value on the right is full 8-bit instruction code.
This forces OpenOCD to update the JTAG IR register on each
transaction even if the instruction in the JTAG IR register
is correct. This causes noticeable performance degradation,
especially with slow JTAG adapters.

The Cortex-A and Cortex-M keeps an arm_jtag struct around just to be
able to pass a pointer to it to one common JTAG function which anyway
only uses the TAP field.
Refactor the function to take a TAP directly, remove the legacy struct
from cortex instances and store the TAP pointer only in the DAP.
Cortex-M makes a call to arm_jtag_setup_connection() with the struct
but the function does nothing useful for a Cortex-M target so remove
the call.

Changes from the flat namespace to heirarchical one. Instead of writing:
#include "jtag.h"
the following form should be used.
#include <jtag/jtag.h>
The exception is from .c files in the same directory.
Removes unused arm_jtag_buf_* helpers from arm_jtag.[ch]. These could
reappear if patches are provided to conver the tree to use them, but
this code should not be in the master tree until that series is ready.
- cleaned up headers to match rest of code
- added missing svn props for previously added files
git-svn-id: svn://svn.berlios.de/openocd/trunk@987 b42882b7-edfa-0310-969c-e2dbd0fdcd60
- added access to ARM920T vector catch register (via generic register mechanism)
- don't disable linefills on ARM920T cores - this lead to lockups when accessing lines already contained in cache
- read content of ARM920T cache and tlb into file (arm920t read_flash/read_mmu commands)
- memory reading improved on ARM7/9, can be further accelerated with new "arm7_9 fast_memory_access enable" command (renamed from fast_writes)
- made in_handler independent from in field (makes the handler more flexible)
- added timeout to ft2232 when using D2XX library
- fixed STR7x protection bit handling on second bank (thanks to Bernard)
- added support for using the OpenOCD on AT91RM9200 systems (thanks to Anders Larsen)
- fixed AT91SAM7 flash handling when not running from 32kHz clock (thanks to Anders Larsen)
