PrPMC800 interrupt problem

A better solution is perhaps to change openpic_init from

        if (NumSources == 0)
                openpic_set_sources(0,
                                    ((t & OPENPIC_FEATURE_LAST_SOURCE_MASK) >>
                                     OPENPIC_FEATURE_LAST_SOURCE_SHIFT) + 1,
                                    NULL);

to

        if (NumSources == 0) {
                int irqs;
            irqs = ((t & OPENPIC_FEATURE_LAST_SOURCE_MASK) >>
                                     OPENPIC_FEATURE_LAST_SOURCE_SHIFT) + 1;
            if (irqs < OpenPIC_NumInitSenses) {
              // Some internal interrupt is defined, init it's vector as well
                  irqs = OpenPIC_NumInitSenses;
        }
                openpic_set_sources(0, irqs, NULL);
     }

Any insight is welcome! As far as I can see, open_pic.c does not handle
timer, ipi, uart or any other internal interrupt sources (as they are not
reported in the feature register).
