Added missing breakpoint/watchpoint implementation to dsp563xx target.
Implementation is not yet complete, which means it does not leverage all
available features of the once debug interface.
This does NOT use the openocd breakpoint/watchpoint command because of
the "special" memory address spaces (X/Y/P/L) of the 56k DSP series.

Remove dummy implementations from all targets except arm7_9 and mips, which
are the only ones with real implementations. Replace with a single default
implementation simply calling target_write_memory().

Target events are added to get better gdb support. The run
algorithm functionality are implemented to support feature
fast flash write functionality. The new r/w buffer api is now
used to support the special memory address handling. The output
of the md command was fixed.
This patch add rudimentary gdb support. The gdb register list
order is corrected. All registers are now 32bit width. Events are
send to signalize gdb the current target status. Resume and step
function was corrected to consider a modified pc register. Read/write
memory now support L memory type, this means a memory with alternating
y/x memory words. The memspace variable, used by gdb, is now observed
before a default memory access is initiated. Dummy functions for breakpoint
and watchpoint are added.
This patch move the dsp563xx_target_create function to the
related code block. Also the target examine function was added
and the register cache is initialized in a separate function. The
missing functionality to invalidate the x memory context on memory
writes was also added.
Hello,
this patch add commands to access to x,y and p memory. For run time optimization some local jtag
function was changed to static inline.

Mathias
Hello,
this patch adds the missing cpu registers and the correct read/write register functions and fixed
most of the halt/step/resume issues. The complete missing error propagation was added.
+ fix tab/spaces

jtag_get/set_end_state() is now deprecated.
There were lots of places in the code where the end state was
unintentionally modified.
The big Q is whether there were any places where the intention
was to modify the end state. 0.5 is a long way off, so we'll
get a fair amount of testing.

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.

When a DSP563xx-aware GDB asks OpenOCD for target registers,
the result should be a GDB with register data ... not an
OpenOCD crash.
(Note that mainline GDB doesn't currently support this core,
so for now, this requires a GDB with FreeScale patches.)
