[PATCH] powerpc: Enable coherency for all pages on 83xx to fix PCI data corruption
On the 83xx platform to ensure the PCI inbound memory is handled properly we have to turn on coherency for all pages in the MMU. Otherwise we see corruption if inbound "prefetching/streaming" is enabled on the PCI controller.
