   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
