ba09901130 Update copyrights to Y2K.
93cx6.c:
	Make the SRAM dump output a little prettier.

aic7xxx.c:
	Store all SG entries into our SG array in kernel space.
	This makes data-overrun and other error reporting more
	useful as we can dump all SG entries.  In the past,
	we only stored the SG entries that the sequencer might
	need to access, which meant we skipped the first element
	that is embedded into the SCB.

	Add a table of chip strings and replace ugly switch
	statements with table lookups.

	Add a table with bus phase strings and message reponses
	to parity errors in those phases.  Use the table to
	pretty print bus phase messages as well as collapse
	another switch statement.

	Fix a bug in target mode that could cause us to unpause
	the sequencer early in bus reset processing.

	Add the 80MHz/DT mode into our syncrate table.  This
	rate is not yet used or enabled.

	Correct some comments, clean up some code...

aic7xxx.h:
	Add U160 controller feature information.

	Add some more bit fields for various SEEPROM formats.

aic7xxx.reg:
	Add U160 register and register bit definitions.

aic7xxx.seq:
	Make phasemis state tracking more straight forward.  This
	avoids the consumption of SINDEX which is a very useful register.

	For the U160 chips, you must use the 'mov' instruction to
	update DFCNTRL.  Using 'or' to set the PRELOADED bit is
	completely ineffective.

	At the end of the command phase, wair for our ACK signal
	to de-assert before disabling the SCSI dma engine.  For
	slow devices, this avoids clearing the ACK before the
	other end has had a chance to see it and lower REQ.

5a151d297c Correct an invalid (and unused) #define in 93cx6.c
Freeze the transaction queue for any type of scsi status other than "okay".

3bafc9d432 Massive overhaul of the aic7xxx driver:
- Convert to CAM
 - Use a new DMA based queuing and paging scheme
 - Add preliminary target mode support
 - Add support for the aic789X chips
 - Take advantage of external SRAM on more controllers.
 - Numerous bug fixes and performance improvements.
