[Resending because I made a mistake when calling git send-email causing the barebox ML to be dropped] This patch set adds support for PCIe controllers found on Marvell EBU SoCs. First, it fixes mvebu-mbus to properly compute resources from DT and extends pci_scan_bus for 64-bit BAR detection. Then it prepares PCI framework to allow to access the host controller struct from struct pci_bus and set a non-zero bus number. Also, a DT helper for parsing devfn number is imported from Linux. Finally, it adds the PCIe host controller driver and SoC specific PHY setup (for Armada 370 only yet) allowing to access PCI devices attached to it. I have tested the driver on Armada 370 Mirabox on both mini-PCIe slot and on-board USB 3.0 controller. The dts is missing reset-gpios properties for gpio1.28 and gpio1.22 respectively. A corresponding patch to add them to armada-370-mirabox.dts will be sent on Linux ML. As soon as I get barebox running on Dove and Kirkwood boards with accessible/populated PCIe slots, I'll add PHY support for those. For Armada XP, I still struggle to fully understand the DT binding which IMHO allows to configure both available ports to Nx1 but not to 1x4. Anyway, I don't have an Armada XP board available, but maybe Thomas or Ezequiel can shed some light into it.
