+	  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().
