I'd like the imote2.cfg added to the target library. How is the attached patch?

Are you saying that 1109 works?
If not, what is the last version of OpenOCD SVN that works?
Does 1036 work...? It messed around with the run_algorithm stuff....
Could you double check that there is a difference between 1109 and
1112 for your case. It doesn't make any sense based upon the changelog...
Also, I discovered some obsolete code for forcing breakpoints in xscale.c that
I've deleted in the attached patch.
