[PATCH 00/16] PCI: support non 1:1 mappings

[Sascha Hauer]

This series evolved from getting PCIe to work on a RK3568 based board.
The device tree PCIe ranges property uses non 1:1 mappings between CPU
and PCI bus which this series adds support for. With this series we
parse the ranges property into struct resource_entry windows like done
in Linux. With this we get pcibios_resource_to_bus() and
pcibios_bus_to_resource() to translate between the PCI/CPU address
spaces. Additionally we have some cleanup for the pcie-designware driver
and we can remove the quirk we already introduced for the rk3588 Rock5b
board in which we have overwritten the ranges property.
