Gr{oetje,eeting}s,
We're assigning PE numbers after the completion of PCI probe. During
the PCI probe, we had PE#0 as the super container to encompass all
PCI devices. However, that's inappropriate since PELTM has ascending
order of priority on search on P7IOC. So we need PE#127 takes the
role that PE#0 has
We need add PE to its own PELTV. Otherwise, the errors originated
from the PE might contribute to other PEs. In the result, we can't
clear up the error successfully even we're checking and clearing
errors during access to PCI config space.
