21 * This intentionally only registers SCIF ports 0, 1, and 3. SCIF 2
22 * INTEVT values overlap with the FPU EXPEVT ones, requiring special
23 * demuxing in the exception dispatch path.
25 * As this overlap is something that never should have made it in to
26 * silicon in the first place, we just refuse to deal with the port at
27 * all rather than adding infrastructure to hack around it.
