f7fe07b585 Introduce NCB_SCRIPT_PHYS and CCB_PHYS macros to find physical addresses
of NCR script labels and of command control block structure components.
This allows for easy modification of the actual virtual to physical
mapping operator used ...
Make all applicable references to physical address values use the above
macros instead of calls to vtophys().

1be758653e Put back p_script component into NCR control block.
The driver currently doesn't use it, but ncrcontrol needs it
to print some script addresses relative to the script start.

b564b3e73e Don't use vtophys() for constant addresses, cache the translations in
the NCR control block (ncb) and command control block (ccb) instead.

ab14793833 Applied patches that make the driver compile on NetBSD again.
They shouldn't affect FreeBSD, since they are within #ifdef NETBSD
directives.
Changed the HAD_ERROR return code into COMPLETE according to a comment
in "/sys/scsi/scsiconf.h"

3a5a6263e3 Add support for 16 targets on WIDE SCSI bus.
This seems to work fine on my 53c810, but really should be tested on
a 53c825 with at least one target set to an ID >= 8.
The script is now copied to memory mapped using vm_page_alloc_contig(),
since it has to be physically contigous. This must be changed, if the
driver is converted into a loadable module !
Two of the probe messages are suppressed, unless "bootverbose" is set.

8befc21fbd The NCR script has grown beyond one page (4KB). Since malloc() returns
contiguous memory in virtual space, but doesn't guarantee any particular
physical layout of pages, the script may be not contguous in physical
memory. This made the first write command fail in very rare cases.
This has been fixed by checking the region returned by malloc() for
being contiguous, but there should be a physical memory allocate
and later mapping to virtual memory instead.

A few assertions and error messages are improved.

07b1c6b3c9 Remove hard coded assumption that SCSI busses have 7 targets.
This change forces the controller drivers to allocate a scsibus_data struct
via a call to scsi_alloc_bus(), fill in the adapter_link field, and optionally
modify any other fields of the struct.  Scsi_alloc_bus() initializes all fields
to the default, so the changes in most drivers are very minimal.  For drivers
that support Wide controllers, the maxtarg field will have to be updated to
allow probing of all targets (for an example, look at the aic7xxx driver).

Scsi_attachdevs() now takes a scsibus_data* as its argument instead of an
sc_link*.  This allows us to expand the role of the scsibus_data struct for
other bus level configuration setings (max number of transactions, current
transaction opennings, etc for better tagged queuing support).

57da02d3f3 Changes to support some CDROM drives and the Quantum Grand-Prix
series of hard disk drives, which don't accept any SCSI message
within an REQUEST SENSE command (i.e. even not an IDENTIFY to set
the LUN).
This patch obviates the need for QUIRK_NOMSG and thus all of the
device_tab[] entries in the NCR driver.

cb09d35cb0 Added a new field to the pci_device struct called pd_shutdown to specify
a device specific shutdown routine for devconf. Assign the value of this
to the kern_devconf struct. Implement a device shutdown routine for if_de
that disables the device. This will stop the device from corrupting memory
after a reboot.
