put a size limitation of the PCI region to map. That makes the PERC 3/Di
raid controller usable, as it publishes too much PCI memory for us to map
in the kernel virtual memory. As we only access the first 256 byte it is
of no use to map 128MB of kvm.

Add support for PPR negotiations and DT transfers,
and the preservation and restoration of the
SCNTL4 register which controls Ultra3 transfers.
Redo sync lookup, since the same period factor
can mean two things depending on whether you are
using DT or ST. Keep a minimum allowed ST period
factor, and a minimum allowd DT period factor for
each adapter.
Currently NO support for QAS or IUS or AIP.

either or both channels on the 53c1010. U3W/U160 support coming.
The particulars of 53c1010 support was derived from the FreeBSD/Linux
sym-2 driver under development by Gerard ROUDIER (groudier@FreeBSD.org).
This first support ensures that registers and bits now reserved are
not used by the 53c1010. It uses the new DFBC register to obtain
DMA FIFO relics.
A single new feature (SF_CHIP_C10) was added, rather than a new
feature for each change the 53c1010 incorporates.
These changes were sufficient to get the imbedded 53c1010 on a Tyan
S2510U3NG board to support installation of OpenBSD to a Quantum Atlas
10K2 drive, and several subsequent 'make build' and 'make release'
cycles using disks on both channels, with and without
softupdates.
More 53c1010 specific code is yet to be extracted from sym-2,
including the changes necessary to enable U160.

results on one line, during boot polling only.
Force wide/sync negotiations for all targets during boot.
Delete extraneous name field and associated strings that duplicate
info provided in INQUIRY data.
Actually timeout during polling rather than wait forever for
ITSDONE.
Remove unneeded check for SCSI_POLL before calling scsi_done(). Makes
logic conform to other drivers.

Written for NetBSD by Manuel Bouyer.
Tested with various cards on i386 and alpha.
Outstanding issue: doesn't work with PowerPC yet.
