Thanks a lot for the report, very useful. I haven't yet looked at the
PCI commit itself, but reading the commit log indicates that it plays
with sizing the BARs, and we're doing some fairly funky stuff with this
in pci-mvebu, so I'm not entirely surprised such a commit can break
stuff. I'll have a look tomorrow.

Thanks!
