didn't verify that hard wired scsi busses would work, but did verify
that hard wired aha addresses did work to a limited extent. Both
aha0 and aha1 must be hardwired, or when the card that was in aha0
goes away, the probe for aha0 might pick up the card that otherwise
would have been aha1.

in cyopen() were done in a different order than in sioopen(), partly
to (ab)use a side effect of comparam() and partly because I didn't
understand what the reset was doing (it flushes the fifos). This
turned out to be more than a cosmetic problem. Flushing the fifos
quite late is good for discarding input that arrived while the line
state was being initialized, and in the cy driver it also seems to
reduce a problem with input that arrived long ago during the previous
close (the UART loses sync too easily and for too long).
The optimisation of only waiting before issuing new commands is
obviously invalid in general and it caused many errors in NIST-PCTS.
I think the errors were mostly for characters sent with the wrong
parity, etc., after a half complete tcsetattr().
Use microtime() instead of a magic loop count to limit the wait.
The wait is a busy-wait :-( and normally takes about 500 usec.
almost works properly. Unfortunately, there is no way to flush
the rx fifo without resetting the channel, which also flushes the
tx fifo. We avoid resetting even when both fifos need to be flushed,
since resetting seems to cause the rx to lose sync if it is done
while data is arriving.

floppy is used on the toshiba Libretto line of subnotebook computers.
It differs from a normal floppy in that you must use PIO rather than
DMA to transfer the data.
To enable this, you must add options "FDC_YE" to your kernel. I don't
have a machine that has a floppy and a pcmcia slot to test to make
sure that this doesn't impact normal floppy units, so I've left this as
an option.

This fixes the symptom and not the cause.
The right answer is to let the PCI system know that the attach failed,
or to fail earlier (in the PCI probe).
The attach() is a void fn() so it can't return failure..
