I apologize for not being clearer. This patch depends on:

PCI/ACPI: Extend pci_mcfg_lookup() responsibilities
PCI/ACPI: Check platform-specific ECAM quirks

These patches from Tomasz Nowicki were previously in your pci/ecam-v6
branch, but that seems to have come and gone. How would you like to
proceed?

That looks great, thank you. The earlier PCI HDL and SoC vendors can be
made aware of such problems, the better.

Thanks,
