There're 2 types of PCI bus sensitive PEs: (A) The PE includes
single PCI bus. (B) The PE includes the PCI bus and all the subordinate
PCI buses, and the patch tries to assign I/O and MMIO resources
based on created PEs. Fortunately, we figured out unified scheme
to do resource assignment for all types of PCI bus based PEs according
to Ben's idea:
- Resource assignment based on PE from top to bottom.
- The soureces, either I/O or MMIO, of the PE are figured out
from the assigned PCI bus.
- The occupied resource by parent PE could possibilly be overrided
by children PEs.
