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=20
in the probe where ATA knows it deals with a Promise chip it also knows=20
how to use that resource as memory space.
