* Move build and debug tools to 'cctools' directory.Keith Packard2009-06-04
| | | | | | These tools were merged in from the ccdbg package. Signed-off-by: Keith Packard <keithp@keithp.com>
* Save/restore registers to host during memory operations. Cache ROM data.Keith Packard2008-12-30
| | | | | | | | | | | Because the debug port uses instructions for most operations, the debug code will clobber registers used by the running program. Save and restore these to avoid corrupting application data. If the ROM file is known, use that to return data instead of fetching it from the target to improve performance.

* Switch to libusb-1.0 and use async interface.Keith Packard2008-12-26
The async libusb interface offers substantial performance benefits by not making each command wait for the reply. This makes talking over this interface almost reasonable. Signed-off-by: Keith Packard <keithp@keithp.com>
