bouyer 863014523a - split siop.c in script-dependant vs script-independant part, for
comming esiop
- add a reset callback for bus-dependant registers settings

bouyer 3bb9a5f666 - do sync/wide negotiation
- use a circular queue for the start slots, so that order has better chances
  to be preserved.

bouyer bf7a94ec2b Fix copyrigth notice. 2000-04-27 14:06:57 +00:00
bouyer 88be4752d0 - Change the script to start new commands in an asyncronous way, using
'command slots' in which the host can put command and wait for the script
 to start them
- Change siop.c to do full disconnect/reslelect, allowing as much as one
 command per target/lun to run in parallel.
- Fix bug in registers init where a board without BIOS would end at
  ID 0 (now the driver works on alpha too).
- better handling of messages, sending back a MSG_EXT_SDTR in response to an
  incoming MSG_EXT_SDTR, and MSG_MESSAGE_REJECT for unhandled messages.
- fix use of bus_dmamap_sync() and htole32().
- supports shared interrups
- change some int8 and int16 to int, for alpha and mips benefits ( suggested by
  Toru Nishimura)

bouyer 19ada4a82a Snapshot of work in progress: new driver for the NCR 53c8xx SCSI controller
(the name 'siop' is still being discussed, may change).
Only basic disconnect/reselect for now, no sync/wide negotiation.
Tested with 810A, 875 and 895 on i386 only.
The bus-independant part should also be able to handle the 53c720 and 53c770.
A new driver with enhanced script should appear for the 825/875/895 'soon'.
