1 * Freescale 83xx and 512x PCI bridges
2
3 Freescale 83xx and 512x SOCs include the same pci bridge core.
4
5 83xx/512x specific notes:
6 - reg: should contain two address length tuples
7     The first is for the internal pci bridge registers
8     The second is for the pci config space access registers
