commit 825da4e9cec68713fbb02dc6f71fe1bf65fe8050 upstream.
Commit c7a75d07827a ("PCI: xgene: Fix IB window setup") tried to fix the damages that 6dce5aa59e0b ("PCI: xgene: Use inbound resources for setup") caused, but actually didn't improve anything for some plarforms (at least Mustang and m400 are still broken).
Given that 6dce5aa59e0b has been reverted, revert this patch as well, restoring the PCIe support on XGene to its pre-5.5, working state.

Hi Greg,
I don't think it makes sense to apply this to 5.10.y, 5.15.y & 5.16.y w/o also applying a backport of 1874b6d7ab1, because without that we will regress support for Stéphane's X-Gene2-based systems. The backport of 1874b6d7ab1 was rejected for these trees because it doesn't apply cleanly, but I've just submitted new versions that do.
Where were those patches sent to? I don't seem to see them on the stable list, did I miss them?
These are the message IDs: 20220405142505.1268999-1-dann.frazier@canonical.com 20220405153419.1330755-1-dann.frazier@canonical.com
I've just bounced them directly to you as well. Thanks Greg!
Got them now, vger was being a bit slow due to the onslaught of patches I had sent it.
