Subject:    [PATCH v5 11/12] ARM: mvebu: Relocate Armada 370 PCIe device tree nodes
From:       ezequiel.garcia () free-electrons ! com (Ezequiel Garcia)

Now that mbus has been added to the device tree, it's possible to
move the PCIe nodes out of internal registers, placing it directly
below the mbus. This is a more accurate representation of the
hardware.
