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,
Michal

Early printk has been removed already that's why this setting doesn't make
any sense. Also change printk level from pr_info to pr_err.

There is no reason to keep empty headers if asm-generic one can be used
instead. That's why remove empty file and use asm-generic equivalent.
cputable.h is completely unused that's why remove it.

boot_cpuid is not used on uni processor system that's why can be removed.

The whole implementation is done in asm-generic/cmpxchg.h file and there is
no reason to duplicate it.
Also do not include asm-generic/cmpxchg-local.h because it is already
included from asm-generic/cmpxchg.h

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.

can you please suggest changes which could be done?

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.

Thanks Rob.

Bharat: Can you please take a look?

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