+ This is the address of PCI configuration space. It can be set up
+ amost anywhere. Before it is set up, it is possible to access PCI
+ configuration space through I/O access, but memory access is more
+ convenient. Using this, PCI can be scanned and configured. This
+ should be set to a region that does not conflict with memory
+ assigned to PCI devices - i.e. the memory and prefetch regions, as
+ passed to pci_set_region().
