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.

The earlier PCI HDL and SoC vendors can be made aware of such problems, the better. Thanks, Cov
