value for same. Make slightly less lame the wwn seed construction.

Remove calls to alpha_register_pci_scsi(). After Mike's recent boot
changes, it no longer exists and is preventing alpha kernels from building.

Organize things to cope with the (possible) lack of downloadable
firmware a bit better.

Add in inclusion of machine/md_var.h (so alpha_scsi_bus_register or what
have you is prototyped). Removed code versions in md struct- not used
any more. Allocate transfer dma maps and xflist stuff in mbxdmasetup based
upon isp->isp_maxcmds. Allow for multiple calls to mbxdmasetup (for
isp_reset cases).

remove unnecessary includes

$Id$ -> $FreeBSD$

Cast pointers to uintptr_t instead of casting them to u_long, and/or vice
versa. Cosmetic.

Set some correct return values. Prefer I/O map all the time unless configured
otherwise.

Properly set the alignment argument to bus_dma_tag_create(). If we
don't care about the alignment, set it to 1, meaning single byte alignment.

add in a boot environment isp_disable flag

Wow- too much breakage..wait until you compile it, buckwheat...

Oops- got sense of ifdef wrong

Remove pre-CAM code. Add in getenv_int calls for variables isp_mem_map,
isp_io_map, isp_no_fwload, isp_fwload, isp_no_nvram, isp_fcduplex
which are all bitmaps of isp instances that should or shouldn't
map memory space, I/O space, not load f/w, load f/w, ignore nvram,
not ignore nvarm, set full duplex mode. Also have an isp_seed value
that we can use to generate a pseudo seed for a synthetic WWN.
Other minor cosmetic cleanup. Add in support for the Qlogic ISP
2200. Very important change where we actually check now to see
whether we were successful in mapping request and response queues
(and fibre channel scratch space).

Clean up 2.2.X support (which might have to be cleaned up again
after some of the previous commits). Add in support for the 1240

Simplify the COMPAT_PCI_DRIVER/DATA_SET hack. We can add:
#define COMPAT_PCI_DRIVER(name,data) DATA_SET(pcidevice_set,data)
.. to 2.2.x and 3.x if people think it's worth it. Driver writers can do
this if it's not defined. (The reason for this is that I'm trying to
progressively eliminate use of linker_sets where it hurts modularity and
runtime load capability, and these DATA_SET's keep getting in the way.)

Use COMPAT_PCI_DRIVER() for registration if it exists. This shouldn't
hurt the driver portability to 3.x too much for where drivers are shared.

Staticize.

Read the board revision and trim cache line size back from 16 to 1
for early revision 2100 boards. Make sure to turn ROM off for these
boards.
