as used on later arm26 system (A5000, A4, A3010, A3020, A4000). What we have got: ... upc0 at iobus0 base 0x010000: config state bb 87 1c 00 00 fdc at upc0 offset 0x3f4 not configured wdc0 at upc0 offset 0x1f0 lpt0 at upc0 offset 0x278 com0 at upc0 offset 0x3f8: ns8250 or ns16450, no fifo ... What we haven't got: - FDC support (found, but not configured). - Clearing lpt interrupts on arm26 systems (needs help from IOEB). - A upc(4) manual page. - More than minimal testing (my A3020s don't have root devices). - A proper probe routine (arm26 can't use one anyway).
