Well, MIPS just like other sane architectures has no concept of ioports. So if there ever is something that's called an ioport on MIPS then it's really a memory location in a memory address range where other PCish devices are living, too. So typically those memory addresses are translated to an actual ioport access by a PCI bridge. There are a few systems where this concept just apply easily such as DECstations, so there we simply claim the device such as the RTC in this case is memory mapped.
