Release 4.12 drivers/scsi/zorro7xx.c
/*
* Detection routine for the NCR53c710 based Amiga SCSI Controllers for Linux.
* Amiga MacroSystemUS WarpEngine SCSI controller.
* Amiga Technologies/DKB A4091 SCSI controller.
*
* Written 1997 by Alan Hourihane <alanh@fairlite.demon.co.uk>
* plus modifications of the 53c7xx.c driver to support the Amiga.
*
* Rewritten to use 53c700.c by Kars de Jong <jongk@linux-m68k.org>
