Modified: sys/conf files
Log:
Add depend rule for the now compile time generated aic7xxx register file.

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

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.

1.39 +2 -2 src/sys/i386/eisa/aic7770.c
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.
