amiga and sun3 turned out to not be y2k+3 compliant here. Remove them, as

well as the few userland tools which were only used on these platforms.

- * This file contains only the machine-dependent parts of the
- * Sun3 SCSI driver.  (Autoconfig stuff and DMA functions.)
- * The machine-independent parts are in ncr5380sbc.c
- *
- * Supported hardware includes:
- * Sun SCSI-3 on OBIO (Sun3/50,Sun3/60)
- * Sun SCSI-3 on VME (Sun3/160,Sun3/260)
- *
- * Could be made to support the Sun3/E if someone wanted to.
- *
- * Note:  Both supported variants of the Sun SCSI-3 adapter have
- * some really unusual "features" for this driver to deal with,
- * generally related to the DMA engine.  The OBIO variant will
- * ignore any attempt to write the FIFO count register while the
- * SCSI bus is in DATA_IN or DATA_OUT phase.  This is dealt with
- * by setting the FIFO count early in COMMAND or MSG_IN phase.
- *
- * The VME variant has a bit to enable or disable the DMA engine,
- * but that bit also gates the interrupt line from the NCR5380!
- * Therefore, in order to get any interrupt from the 5380, (i.e.
- * for reselect) one must clear the DMA engine transfer count and
- * then enable DMA.  This has the further complication that you
- * CAN NOT touch the NCR5380 while the DMA enable bit is set, so
- * we have to turn DMA back off before we even look at the 5380.
- *
- * What wonderfully whacky hardware this is!
- *
- * Credits, history:
- *
- * David Jones wrote the initial version of this module, which
- * included support for the VME adapter only. (no reselection).
- *
- * Gordon Ross added support for the OBIO adapter, and re-worked
- * both the VME and OBIO code to support disconnect/reselect.
- * (Required figuring out the hardware "features" noted above.)
- *
- * The autoconfiguration boilerplate came from Adam Glass.
