Quirk handling relies on an idea of matching MCFG OEM ID and OEM revision
(the ones from standard header of MCFG table). Linker section is used

kept self contained.
As an example, last patch presents above mechanism usage for ThunderX PEM
driver.
Tomasz Nowicki (3):
pci, acpi: Match PCI config space accessors against platfrom specific
ECAM quirks.
arm64, pci: Start using quirks handling for ACPI based PCI host
controller.
