powerpc/powernv: Reserve the correct PE number
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 previously. For PHB3, we still have PE#0 as the reserved PE. The patch supposes that the underly firmware has built the RID to PE# mapping after resetting IODA tables: all PELTM entries except last one has invalid mapping on P7IOC, but all RTEs have binding to PE#0. The reserved PE# is being exported by firmware by device tree. Signed-off-by: Gavin Shan <shangw@linux.vnet.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
