[NCLUG] Anyone know the MPC5200 (PPC603e core) CPU?

[Stephen Warren]

I'm working on a project using the MPC5200 chip, and we're trying to get 
DMA-capable IDE drivers up and running under Linux 2.4 (MontaVista 3.1).

DMA for IDE works fine on its own, but it seems pretty much as soon as 
we use the PCI bus (the external address/data pins on the chip are 
shared between IDE and PCI with an arbiter) we get a machine check 
exception due to TEA (basically, the CPU transaction on one of the 
processor's internal busses times out).

Does anyone know anything about this chip, or know of somebody that has 
real low-level detailed knowledge about this kind of thing?

Thanks for any help.
