2  *  Device driver optimized for the Symbios/LSI 53C896/53C895A/53C1010
3  *  PCI-SCSI controllers.
4  *
5  *  Copyright (C) 1999-2001  Gerard Roudier <groudier@free.fr>
6  *
7  *  This driver also supports the following Symbios/LSI PCI-SCSI chips:
8  *	53C810A, 53C825A, 53C860, 53C875, 53C876, 53C885, 53C895,
9  *	53C810,  53C815,  53C825 and the 53C1510D is 53C8XX mode.
10  *
11  *
12  *  This driver for FreeBSD-CAM is derived from the Linux sym53c8xx driver.
13  *  Copyright (C) 1998-1999  Gerard Roudier
14  *
15  *  The sym53c8xx driver is derived from the ncr53c8xx driver that had been
16  *  a port of the FreeBSD ncr driver to Linux-1.2.13.
17  *
18  *  The original ncr driver has been written for 386bsd and FreeBSD by
19  *          Wolfgang Stanglmeier        <wolf@cologne.de>
20  *          Stefan Esser                <se@mi.Uni-Koeln.de>
21  *  Copyright (C) 1994  Wolfgang Stanglmeier
22  *
23  *  The initialisation code, and part of the code that addresses
24  *  FreeBSD-CAM services is based on the aic7xxx driver for FreeBSD-CAM
25  *  written by Justin T. Gibbs.
26  *
