I'd like to get it for the MPC5200 because of the project I am working
on, an open source audio device. It would be nice if there was a cheap
hardware debugger available for hackers to use on it. Maybe one of the
Freescale developers will see this and send me the right docs.

Is it radically different? Dominic has been able to support every ARM
7/9 chip he can get his hands on without too much trouble once the
core support was written. I don't think he has ARM 11 working yet.
