"fsl," prefix on compatible.

Where is #cpus defined or used? I don't see it used in any other trees, either.

Where is 32-bit; defined or used?

Comment doesn't match what's actually in reg.

Is it compatible with any other 85xx memory controller?

Should this node be referenced by an l2-cache property in the cpu node?

Should probably be "fsl,mpc8572-pcie", "fsl,mpc8641-pcie".

No prefetchable mem space?

Decimal would be nicer.

Why is this one 8548-compatible and the previous one 8641-compatible?

Where is the built-in; property defined or used?
