They tell where PCI config space is and how it works.
They tell where PCI I/O and memory space are mapped, and how hardware
byteswapping is done.
They tell that all PCI interrupts of all slots (INT #A-#D) are mapped to =
one
single Zorro interrupt.

Code for configuring PCI devices already exists in the PPC tree.

I guess now we know everything we need to know. Let's implement it :-)
