This patch adds MMIO support to the pata_sil680 for taskfile IOs, based on what the old siimage does. I haven't bothered changing the chip setup stuff from PCI config cycles to MMIO though (siimage does it), I don't think it matters, I've only adapted it to use MMIO for taskfile accesses. I've tested it on a Cell blade and it seems to work fine.
