bbb0896cff
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.
