* Device driver for the SYMBIOS/LSILOGIC 53C8XX and 53C1010 family
* of PCI-SCSI IO processors.
*
* Copyright (C) 1999-2001 Gerard Roudier <groudier@free.fr>
*
* This driver is derived from the Linux sym53c8xx driver.
* Copyright (C) 1998-2000 Gerard Roudier
*
* The sym53c8xx driver is derived from the ncr53c8xx driver that had been
* a port of the FreeBSD ncr driver to Linux-1.2.13.
*
* The original ncr driver has been written for 386bsd and FreeBSD by
* Wolfgang Stanglmeier <wolf@cologne.de>
* Stefan Esser <se@mi.Uni-Koeln.de>
