  1.90      +1 -0      src/sys/conf/files

  Modified:    sys/dev/aic7xxx  aic7xxx.seq aic7xxx_asm.c
  Added:       sys/dev/aic7xxx  Makefile aic7xxx.reg gram.y scan.l
                        sequencer.h symbol.c  symbol.h
  Removed:     sys/dev/aic7xxx  aic7xxx_asm.1 aic7xxx_reg.h
  Log:
  Makefile gram.y scan.l sequencer.h symbol.c symbol.h aic7xxx_asm.c:
  	New sequencer assembler for the aic7xxx adapters.  This assembler
  	performs some amount of register type checking, allows bit
  	manipulation of symbolic constants, and generates "patch tables"
  	for conditionalized downloading of portions of the program.
  	This makes it easier to take full advantage of the different
  	features of the aic7xxx cards without imposing run time penalies
  	or being bound to the small memory footprints of the low end
  	cards for features like target mode.
  
  aic7xxx.reg:
  	New, assembler parsed, register definitions fo the aic7xxx cards.
  	This was done primarily in anticipation of 7810 support which
  	will have a different register layout, but should be able to use
  	the same assembler.  The kernel aic7xxx driver consumes a generated
  	file in the compile directory to get the definitions of the register
  	locations.
  
  aic7xxx.seq:
  	Convert to the slighly different syntax of the new assembler.
  
  	Conditionalize SCB_PAGING, ultra, and twin features which shaves
  	quite a bit of space once the program is downloaded.
  
  	Add code to leave the selection hardware enabled during reconnects
  	that win bus arbitration.  This ensures that we will rearbitrate
  	as soon as the bus goes free instead of delaying for a bit.
  
  	When we expect the bus to go free, perform all of the cleanup
  	associated with that event "up front" and enter a loop awaiting
  	bus free.  If we see a REQ first, complain, but attempt to
  	continue.  This will hopefully address, or at least help diagnose,
  	the "target didn't send identify" messages that have been reported.

  Modified:    sys/i386/scsi  aic7xxx.c
  Log:
  Adapt to some changes in the register definitions.  Clear the selection
  enable in SCSISEQ during error recovery to deal with the way the
  sequencer leaves selections enabled now.  Add code to perform "patching"
  during sequencer program download.
