const char *. Originally I was going to add casts from const char * to
char * in some of the pci device drivers, but the reality is that the
pci device probes return constant quoted strings.

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
indentation conforms to style(9), aka the bruce filter.

but the present PCI probe code still thinks we are there as the pci attach
can't return an error code.
This means we are in the shared interrupt list, but have not been set up.
If we are sharing ints with another device, ohci_intr will be called and will
coredump on a NULL reference. So just return if it is called when not set up.
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
return residual information. It seems that some firmware revisions dislike
S/G ccbs with 0 length S/G lists.
Correct bt_cmd() so that we always honor command status that was latched
by our interrupt routine while polling for completion..
is more robust and common code can be used for both the target and iniator
roles. The mechanism for tracking negotiation state has also been simplified.
Add support for sync/wide negotiation in target mode and fix many of
the target mode bugs running at higher speeds uncovered. Make a first
stab at getting all of the bus skew delays correct. Sync+Wide dataout
transfers still cause problems, but this may be an initiator problem.
Ensure that we exit BITBUCKET mode if the controller is restarted.
Add support for target mode only firmware downloads. This has been
tested on the aic7880, but should mean that we can perform target mode
on any aic7xxx controller. Mixed mode (initiator and target roles in
the same firmware load) is currently only supported on the aic7890, but
with optimization, may fit on chips with less instruction space.
1) Removed 'emulation' of bitmaps in printfs, FreeBSD seems to have caught
up on that one
2) Fixed a few bugs in the timeout/timo timeout variables
3) First attempt at fixing a bug mentioned by Kazu: uhci_run is not able
start/stop his USB host on his motherboard.

suggested compilation cleanups from Eklund. Wire down a hard loop id if we are
not on a platform that has the ability to get to a PCI BIOS (it still will
float to the ID it gets after a LIP but at least we can try). Clarify that the
expanded lun is based upon SCCLUN defines (in f/w).
for possible buffer overflow problems. Replaced most sprintf()'s
with snprintf(); for others cases, added terminating NUL bytes where
appropriate, replaced constants like "16" with sizeof(), etc.
These changes include several bug fixes, but most changes are for
maintainability's sake. Any instance where it wasn't "immediately
obvious" that a buffer overflow could not occur was made safer.

sio.c (rev.1.152) can't be used because there is no status bit for
transmitter-empty. Now ttywait() works right.
