pci-host-generic.c is just for standard PCI implementations, and it

The one thing that could be shared is the ECAM config space access,
but ACPI already needs something else here because it requires
access to the config space at early boot time, way before we even
load that driver, see raw_pci_read/raw_pci_write.
Yes, I agree, basically ACPI has already a concept of "host generic"
layer, there is not much point in "merging" it with the
pci-host-generic.c driver. One thing is for certain: nothing in this
and Tomasz patchsets is
arm64 specific, and should not live in arch/arm64.
Ok so now I guess Tomasz is aware of this and probably he is reworking
his patchset to move his code into "drivers/acpi/pci_*",
Tomasz can you confirm this?
Yes, working on it now and sorry for late response.
Tomasz
