Sorry, you're right. I spent too long reading the OpenOCD source and seeing the IMX51 Freescale references in the broken_cpus array, and then it was late... Yea, I'm using the DM3730 TI processor in the BeagleBoard-xM here, which is being picked up by your logic in that loop incorrectly and a fixup is being applied that should not be applied. <snip commented out code fixup> > This is bogus ...

I was just applying a hack in my local git branch for running the BeagleBoard-xM here with my Flyswatter. That was neither a patch nor intended for use other than with the xM if someone else is using a release of OpenOCD since the beginning of November. I really agree with you that the correct fix is to better determine an IMX51 for fixup. FWIW, I got this wrong at first. I read the archives and assumed that the BeagleBoard was in need of some fixup, but actually it's fine. It's the logic intended to fixup the other part that is breaking Beagle. Oh, and hey, thanks for the followup.
