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

The armdebug project is now dual licensed to make it easier to integrate with the LEGO NXT firmware. You can choose either to use the GPLv2 or the LEGO Open Source License to integrate this into other projects. Misc cleanups: Removed types.h Moved Debugger Macros into its own file to improve readability. Added COPYING, LEGO license and GPL license texts.
