9c0b8410b8 adv_pci.c:
Update list of supported products.
	Adjust probe message to include the ASC3030.

advansys.c:
	Fix a long standing bug in the error recovery strategy.  In order
	to keep recovery simple, we freeze the SIMQ, stopping the XPT from
	submitting new requests.  Unfortunately, we also will freeze the
	SIMQ if bus_dmamap_load blocks or we run out of controller resources.
	On cards with limited resources it was possible to freeze the
	SIM a second time and never unfreeze it.  Now we more carefully
	track our exception state so we never freeze the SIMQ more than
	once.

	Don't rely on pointers fitting in a 32bit field stored in the
	per-transaction data structures on the card.  Use an index to
	an array of transaction mapping structures instead.  This should
	allow this driver to work on the Alpha.

	Deal with the ASC3030 which is almost idistinguishable from the
	ASC3050.  Unfortunately the ASC3030 does not work at Ultra speeds,
	so if we can't find an eeprom, we must assume that ultra is disabled.
	The SIIG cards using the 3030 do not have eeproms.  As a side effect,
	we now honor the ultra disable bit in the eeprom if it is present.

	Don't bother attempting to write corrected eeprom data back to the
	eeprom.  We can function just fine if the data is corrupted and
	I'd rather not risk messing up the user's eeprom.

	Modify the interrupt handler to catch latched external bus rests.

	Dynamically determine the maximum number of S/G elements we can
	map at a single time.  The nature of the firmware interface for
	these cards makes this value dependent on the number of "queues"
	the card can support.

6875d25465 Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not
ready for it yet.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

0a42ab8379 Advanced Systems Inc. SCSI Controller driver and ISA/VL front end.
I have only tested the ABP5140 card and only with a single CDROM drive
but it seems to work fine.  This driver relies on features found only in
the SCSI branch so will not work in -current until those changes
are brought in.  It also doesn't have any error handling code *yet*.
The goal is to use this driver as the development platform for the new
generic SCSI layer error recovery/handling code.

PCI and EISA front ends will show up as soon as I get my hands on
the cards.  There are also a few issues in the driver that I need
to clear up with AdvanSys before I can suggest sticking one of
these cards in your server. 8-)

Thanks to AdvanSys for releasing this code under a suitable copyright.
