2 * Detection routine for the NCR53c710 based Amiga SCSI Controllers for Linux.
3 * Amiga MacroSystemUS WarpEngine SCSI controller.
4 * Amiga Technologies/DKB A4091 SCSI controller.
6 * Written 1997 by Alan Hourihane <alanh@fairlite.demon.co.uk>
7 * plus modifications of the 53c7xx.c driver to support the Amiga.
9 * Rewritten to use 53c700.c by Kars de Jong <jongk@linux-m68k.org>
