Its just a warning from the kernel (which IMHO shouldn't be there). The reason is that "normal" ATA controllers has port space there and the generic part of ATA probes it as part of the generic probe code. Later in the probe where ATA knows it deals with a Promise chip it also knows how to use that resource as memory space.
