The microdev only has to contend with silly PIO mangling on anything within the SuperIO range. As each of the SuperIO modules is already speciail cased, we just shift that logic over to the ioport map. With microdev PCI never being merged (and being fudamentally broken in hardware), and the ethernet chip only doing 16-bit accesses already, there's no need to maintain any of the extra special casing. Kill it all off. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
