Per IEEE Std 1275-1994 bindings documentation (to which kernel DT bindings refers), DT property assigned-addresses contains BDF address of resource. Currently more PCIe Root Port nodes have BDF address in assigned-addresses which points to different PCIe Root Port nodes. This obviously does not make sense as the address resource specified in assigned-addresses of every PCIe Root Port describes address range of internal registers which are specific for corresponding Marvell PCIe Root Port. Fix this issue and align all BDF addresses in assigned-addresses DT property to specify correct BDF address of the current PCIe Root Port. Note that current version of pci-mvebu.c controller driver, which registers Marvell PCIe Root Ports, ignores BDF value in DT property assigned-addresses. It expects that Root Port's assigned-addresses contains address range of that root port. That is why driver currently works without any issue and nobody spotted it. But if driver or something else would do device tree validation then this issue should be spotted and throws error. Also device tree files may be used by other projects where drivers may require correct values. This patch series aligns BDF address of every Marvell PCIe Root Port in node name, config space in reg property and mem in assigned-address property of internal registers resource.
