[PATCH RESEND 0/6] Marvell EBU PCIe driver

[Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com>]

[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.
