The six sets of outbound translation registers allow six simultaneous translation windows to the PCI port.
Software can move and adjust the memory window translations and sizes during run-time. This allows
software to access different PCI memory/IO spaces on-the-fly, but the PCI outbound translation source
windows must not overlap. However, outbound translation destination windows can be overlapped.

The following rules are applied to maintain proper ordering of transactions:

The transactions arriving from each port are dispatched to the destination port in the order of
arrival. The dispatch order of transactions arriving on different ports is not necessarily maintained.
A read transaction that originates at the CSB port and reads from the PCI port pulls out of the IOS
any posted writes that originated on the PCI port and were posted before the read data arrives from
the PCI.
The IOS can always accept a write from the PCI port without forcing the PCI port to first accept a
read.
