Full support for hardware watchpoints, breakpoints and debug counters has been added to the Advanced Debug System. New in this release is the watchpoint GUI client AdvancedWatchpointControl, a Java program which allows a user to graphically configure the watchpoint hardware in the CPU. Want the CPU to break when x == 42? Done. Want to stop on the 157th iteration of that loop? Done. Can't use software breakpoints because your code is running out of ROM? Problem solved.

This support also includes a patch for the OR1200v1 RTL code, which fixes the broken hardware watchpoint support in the CPU. Support for the OR1200v3 has not been included yet, as the v3 is still in development flux.

This update also adds FreeBSD support, courtesy of Wojciech Koszek.

Happy developing, all.
