NetBSD/sys/dev/ic/lpt_upc.c
bjh21 d7eebd9227 Basic driver for CHIPS 82C710 Universal Peripheral Controller and friends,
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).
