2010-12-17use defines instead of hardcoding constants for breakpoint instructionTC Wan
Inline assembly syntax depends on an archaiac gcc feature. Thanks to Stefan B. from EmbDev.net ARM GCC forum for the tip.

2010-12-16fix undef handler instruction address calculation, arm7 does not recognize ↵TC Wan
bkpt instruction coding The Undef handler was adding to instead of subtracting from PC to get the BKPT instruction address. ARM7 does not recognize BKPT instruction coding. Modified instruction code to use UNDEF instruction prefix instead. Refer Steve Furber, ARM SOC Architecture, 2nd Ed, pg 143

2010-12-02changed the license clause, misc cleanupsTC Wan
The armdebug project is now dual licensed to make it easier to integrate with the LEGO NXT firmware.

Misc cleanups: Removed types.h Moved Debugger Macros into its own file to improve readability. Added COPYING, LEGO license and GPL license texts.
