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.
