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
so that quirks can be registered using special macro (see patches) and
kept self contained.
As an example, last patch presents above mechanism usage for ThunderX PEM driver.

Is this series superceded by Dongdong's series of 6/13 ("[RFC,V2,1/2]
ACPI/PCI: Match PCI config space accessors against platfrom specific ECAM
quirks")?
Yes this series had two another versions (v2,v3) posted by someone else.
However, I posted another v4 which is the latest one:
[RFC PATCH v4 0/5] ECAM quirks handling for ARM64 platforms
https://lkml.org/lkml/2016/6/28/165
In v4 there is one minor thing to be fixed. Do you want me to resend it
as v5 including mentioned fix ?
Thanks,
Tomasz
