PCI segment mode and PCI bus mode

PRIMEQUEST supports two PCI bus mapping modes: PCI segment mode and PCI
bus mode.
PCI segment mode
All PCIU interfaces of each IO_Unit can be used.
PCI bus mode
Of the PCIU interfaces of each IO_Unit, only PCI Slot#0 and PCI Slot#1 can be
used.
The mapping mode can be defined for each partition.
Table 2.11 lists the PCI bus mapping modes supported by each operating system.
