Release 4.7 drivers/scsi/zorro7xx.c

Directory: drivers/scsi
/*
 * 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>
