    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
