Quirk handling relies on an idea of matching MCFG OEM ID, TABLE ID and
revision (the ones from standard header of MCFG table).
Static array is used to keep quirk entries. Each entry consist of
metioned MCFG IDs along with custom pci_ops structure and initialization call.
As an example, last patch presents quirk handling mechanism usage for
ThunderX PEM driver.
Tomasz Nowicki (5):
PCI: Embed pci_ecam_ops in pci_config_window structure
PCI/ACPI: Move ACPI ECAM mapping to generic MCFG driver
PCI: Check platform specific ECAM quirks
ARM64/PCI: Start using quirks handling for ACPI based PCI host
controller
PCI: thunder: Add ThunderX PEM MCFG quirk to the list
