o Add some kludges to maybe bring support for 1540A/1542A into the

that has them hasn't given me feedback, I'm making this commit
blind.
o Honor unit numbers that are in the config file now. This allows one
to hard wire the unit numbers (and have high unit numbers for plug
and pray devices, which can't seem to be hardwired) and have the
cards not migrate from aha1 -> aha0 should aha0 go on the fritz. I
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.
The previous code just ignored the invalid map register, but this gave

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.
I have ported this to -current and made an attempt to ensure that the

but the present PCI probe code still thinks we are there as the pci attach

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..
If we are not transfering any data, use a non S/G ccb type that doesn't

use a 256 entry ring buffer of descriptersfor this purpose. This allows
the use of a simple 8bit counter in the sequencer code for tracking start
location.
Entries in the ring buffer now contain a "cmd_valid" byte at their tail.
As an entry is serviced, this byte is cleared by the kernel and set by
the sequencer during its dma of a new entry. Since this byte is the last
portion of the command touched during a dma, the kernel can use this
byte to ensure the command it processes is completely valid.
The new command format requires a fixed sized DMA from the controller
to deliver which allowed for additional simplification of the sequencer
code. The hack that required 1 SCB slot to be stolen for incoming
command delivery notification is also gone.

This reduces mode switching overhead for "polled" mode interrupt handling
