No unfortunately it does not. The way I structured the code the
bridge set-up is carried out in the struct hw_pci.scan() callback and
for mv78xx0 it was not done properly.
As said in the other thread we need a pci_fixup_irqs() removal v3 to
address these issues, given that on some host bridges v2 it is still
untested.
