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