* 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)
	pci0: pci@e0008500 {
		interrupt-map-mask = <0xf800 0x0 0x0 0x7>;
		interrupt-map = <
				/* IDSEL 0x0E -mini PCI */
				 0x7000 0x0 0x0 0x1 &ipic 18 0x8
				 0x7000 0x0 0x0 0x2 &ipic 18 0x8
				 0x7000 0x0 0x0 0x3 &ipic 18 0x8
				 0x7000 0x0 0x0 0x4 &ipic 18 0x8

				/* IDSEL 0x0F - PCI slot */
				 0x7800 0x0 0x0 0x1 &ipic 17 0x8
				 0x7800 0x0 0x0 0x2 &ipic 18 0x8
				 0x7800 0x0 0x0 0x3 &ipic 17 0x8
