On PPC, the default PAGE_SIZE is 64kb. Unfortunately, the hardware alignments don't match here: There are RAM and MMIO regions within a single page when it's 64kb in size. So the only way out for now is to tell the user that he should use 4k PAGE_SIZE. This patch gives the user a hint on that, telling him that failing to register a prefix slot is most likely to be caused by mismatching PAGE_SIZE. This way it's also more future-proof, as bigger PAGE_SIZE can easily be supported by other machines then, as long as they stick to 64kb granularities. Signed-off-by: Alexander Graf <agraf@suse.de>
