+* Freescale 83xx and 512x PCI bridges
+
+Freescale 83xx and 512x SOCs include the same pci bridge core.
+
+83xx/512x specific notes:
+- reg: should contain two address length tuples
+    The first is for the internal pci bridge registers
+    The second is for the pci config space access registers
+
+Example (MPC8313ERDB)
