[v2,0/2] PCI: mvebu: add support for orion soc

Message

Hello all,

Here a cleaned up version of the previous series.

Changes
 - instead of removing PCIe related mvebu windows add them in pcie_setup()

I intentionally left the ORION5X_PCIE_WA_VIRT_BASE in place as all pieces
in the puzzle have not found their place yet. It will be replaced with
ioremap() or similar when the problem of passing the address to
configuration space from a device tree is solved.

Tested with DNS323 both DT and non-DT builds.

Thanks,
Mauri

Hello all, could you please look at the issue how to write
representation of PCIe config space in device tree?
https://lore.kernel.org/linux-devicetree/20220710225108.bgedria6igtqpz5l@pali/

Without it we cannot finish this conversion of orion5x pcie code from
arch/arm to pci-mvebu.c
