Justin T. Gibbs 6b172e59a6 First pass cleanup of this driver. This pass does not include the sequencer
optimizations I have been working on yet, but does bring in some bug fixes
and performance improvments that were easy to regression test:

Setup the data fifo threshold and bus off timing correctly for 27/284x cards.
Users of these adapters with fast periferals (greater than 5MB/s) will notice
a big performance difference. (Sometimes as large as going from 3.7->8.3MB/s).

Fix handling of the active target flags.  Some of the outbs where missing
the base offset in the abort code.  The abort code still needs lots of work.

Support 3940 controllers, but only with 16 SCBs for now.  Eventually I'll
add support for all 255, but I need to find a tester for the code first since
we have to enable the cards external SRAM to do this.

Add Dan Eischen's serial eeprom reading facilities.  This allows the 2940
adapters to pull additional information left over from SCSI-Select right out
out of the configuration seeprom.

If the BIOS is disabled on 274x controllers, reset all target parameters
to there defaults since you can't rely on what is stored in scratch ram.

Report motherboard controllers as such.

Stick the first SG address and count into the SCB data and count areas for
all transfers in preparation of a later sequencer optimization.

Keep track of which targets can are allowed to have the disconnection
priveledge since this will be handled by the kernel driver in the future.

If a target issues a message reject in response to a tagged message,
disable tagged queuing for that target.  Some seagates say they can do
tagged queuing, but lie, and its a shame to have to disable tagged queuing
on all devices just because you have one that can't cope.

This install procedure is ALPHA code, and        `--{__________)
may very possibly *DESTROY* the contents of your
ENTIRE DISK!  Please do not proceed with this installation
unless you've adequately backed up your data first!

If any errors occur during this installation, you can see them
by toggling over to the alternate screen - type ALT-F2 to switch
over, ALT-F1 to switch back to the install screen.  The debugging
output on the second screen may be very valuable to us in understanding
your bug report, so please be sure to take note of it when reporting
any failures in the installation!  Thanks!

Menus and scrolling output windows may be traversed with the arrow
and Page Up/Page Down keys.  To suspend the installation at any point,
hit ESC twice.  Hitting TAB will move the focus to different controls.
If you've ever dealt with a DOS installation, you'll know how to deal
with this.

For a more complete description of what's new in this release, please
see the release notes.

For more documentation on this system, it is recommended that you purchase
the 4.4BSD Document Set from O'Reilly Associates and the USENIX Association.
ISBN 1-56592-082-1  We have no connection with O'Reilly, we're just
satisfied customers!

Have fun, and please let us know of any problems you encounter with
this release!

Comments should be sent to:

Bug reports should be sent using the `send-pr' utility, if you
were able to get the system installed, otherwise to:

	bugs@FreeBSD.org

And general questions to:

Please have patience if your questions are not answered right away -
this is an especially busy time for us, and our volunteer resources
are often strained to the limit (if not somewhat past!).

Thanks!
