Quoting Bjorn's original reply to the previous series:

Some of the code that moved to drivers/acpi/pci_mcfg.c is not
really ACPI-specific, and could potentially be used for non-ACPI
bridges that support ECAM.  I'd like to see that sort of code
moved to a new file like drivers/pci/ecam.c.

So my guess is that this is the reasoning behind JC's file layout.

I'm curious what Lorenzo's take on things is currently. I assume this
series is now to be the official coordinated version of this effort for
upstream, following the advice of Bjorn previously, but I would like to
know if everyone is behind this plan. I've (previously) requested a
Linaro LEG meeting this week (part of our bootarch working group) to
specifically discuss the status of PCI upstreaming in order to get the
different vendors together to ensure every single one of them is
tracking the correct latest effort and doing what is needed to test/aid,
hence my ask. If this is now plan A, I'll make sure everyone is aligned
behind it and start pinging people individually for testing.

My take is that JC's aim is to get this four patch series reviewed and
merged (which is *not* sufficient to get ACPI PCI to work fully on ARM64
- see cover letter - the remaining patches in his branch are not
fixes, it is code that is required to get things to work, these 4
patches stand alone are not sufficient but I understand he wants to get
them reviewed following feedback on the lists) so that we can make
progress on ACPI PCI on ARM64.

I will comment on the patches as soon as I have time to review
them, I certainly would like to understand what we have to do with the
rest of the code though (provided this series is good to go) see above.
