I asked about PCI Express for 85xx on the list recently and was informed "You do not need to specify TLB/LAW for PCI-X. it uses the same memory map as PCI1."
In your first Email you used the term PCI-X in your questions. Only the Subject mentioned PCI Express (PCIe). There is a big difference between PCI-X and PCIe! Maybe this is the reason for the confusion?
My bad! Wikipedia says PCI Express is "officially abbreviated as PCI-E or PCIe" . Too many acronyms closely resembling each other...
I think, Zang Roy referred to PCI-X (as stated) and not PCIe in his answer you quoted above.
What is the PEX TLB entry for? The mpc8548cds docs in the git repo haven't been updated yet.
As far as I know, PCIe needs an own memory range - at least if it should be used in parallel with "normal" PCI.

Thanks! That was the info I was looking for. Robert
