 o Convert to <inttypes.h> style fixed sized types to facilitate porting to
   other systems.

 o Normalize copyright text.

 o Clean up probe code function interfaces by passing around a single
   structure of common arguments instead of passing "too many" args
   in each function call.

 o Add support for the AAA-131 as a SCSI adapter.

 o Add support for the AHA-4944 courtesy of "Matthew N. Dodd" <winter@jurai.net

 o Correct manual termination support for PCI cards.  The bit definitions
   for manual termination control in the SEEPROM were incorrect.

 o Add support for extracting NVRAM information from SCB 2 for BIOSen
   that use this mechanism to pass this data to OS drivers.

 o Properly set the STPWLEVEL bit in PCI config space based on the
   setting in an SEEPROM.

 o Go back to useing 32byte SCBs for all controllers.  The current
   firmware allows us to embed 12byte cdbs on all controllers in
   a 32byte SCB, and larger cdbs are rarely used, so it is a
   better use of this space to offer more SCBs (32).

 o Add support for U160 transfers.

 o Add an idle loop executed during data transfers that prefetches
   S/G segments on controllers that have a secondary DMA engine
   (aic789X).

 o Improve the performance of reselections by avoiding an extra
   one byte DMA in the case of an SCB lookup miss for the reselecting
   target.  We now keep a 16byte "untagged target" array on the card
   for dealing with untagged reselections.  If the controller has
   external SCB ram and can support 64byte SCBs, then we use an
   "untagged target/lun" array to maximize concurrency.  Without
   external SCB ram, the controller is limited to one untagged
   transaction per target, auto-request sense operations excluded.

 o Correct the setup of the STPWEN bit in SXFRCTL1.  This control
   line is tri-stated until set to one, so set it to one and then
   set it to the desired value.

 o Add tagged queuing support to our target role implementation.

 o Handle the common cases of the ignore wide residue message
   in firmware.

 o Add preliminary support for 39bit addressing.

 o Add support for assembling on big-endian machines.  Big-endian
   support is not complete in the driver.

 o Correctly remove SCBs in the waiting for selection queue when
   freezing a device queue.

 o Now that we understand more about the autoflush bug on the
   aic7890, only use the workaround on devices that need it.

 o Add a workaround for the "aic7890 hangs the system when you
   attempt to pause it" problem.  We can now pause the aic7890
   safely regardless of what instruction it is executing.
