The Armada XP SoCs have multiple PCIe interfaces. The MV78230 has 2 PCIe units (one 4x or quad 1x, the other 1x only), the MV78260 has 3 PCIe units (two 4x or quad 1x and one 4x/1x), the MV78460 has 4 PCIe units (two 4x or quad 1x and two 4x/1x). We therefore add the necessary Device Tree informations to make those PCIe interfaces usable.
