I am sending this series as before SMP support.
Most of these patches are clean ups and should be easy to review them. I
expect there will be more discussions about SMP support.
There could be some optimization added based on
https://lkml.org/lkml/2020/2/10/1528
Thanks,

While not really related to adding SMP, any chance you or someone
could look at moving microblaze PCI support to drivers/pci/? I suspect
much of the code should drop out as we have common helpers for much of
it now. That would leave only powerpc and mips for DT+PCI platforms.

Look at the host controller drivers in drivers/pci/controller/.
pci-host-{generic,common}.c is a good template to start with as that's
a controller with standard config space accesses and no h/w setup
needed. Essentially you need to call devm_pci_alloc_host_bridge(),
pci_parse_request_of_pci_ranges() and pci_host_probe() with whatever
h/w setup you need in between those calls.
Looking at the microblaze PCI code, looks like you may need custom
config space accessors which is quite common. Probably all the
resource and device scanning can be removed. If you look at arm64, all
the arch PCI code is just for ACPI.

Hi Rob,
Can you please let us know why we might need custom config space accessors ?
We tested pci_generic_config_read/write accessors on microblaze, and we
did not see any issues.

Bharat

I was thinking maybe the indirect code might have to be custom, but
maybe everything can be handled in .map_bus().
