You seem to have virtual-reg properties on a *lot* of nodes, are they
really necessary? virtual-reg should be used *only* for things which
you need to access very early in the bootwrapper. Usually that's only
the serial port for the console. Come to that, the CPU is a 750 which
has a real mode, so it seems dubious that you would need any
virtual-reg values at all.

If you're using the "label" property, it would be normal to name the
nodes simply "[EMAIL PROTECTED]".

This device_type value should not be here.

This needs some sort of "compatible" value.

What is this device? It needs some sort of "compatible" value.

This device_type value shouldn't be here either.

Two PCI bridges with identical bus-range values seems potentially
problematic...

The dts file should not include a "bootargs" value. The wrapper will
fill that in from the kernel config.
