** High Performance device driver for the Symbios 53C896 controller.
**
** Copyright (C) 1998-2001 Gerard Roudier <groudier@free.fr>
**
** This driver also supports all the Symbios 53C8XX controller family,
** except 53C810 revisions < 16, 53C825 revisions < 16 and all
** revisions of 53C815 controllers.
**
** This driver is based on the Linux port of the FreeBSD ncr driver.

**-----------------------------------------------------------------------------
**
** The Linux port of the FreeBSD ncr driver has been achieved in
** november 1995 by:
**
** Gerard Roudier <groudier@free.fr>
**
** Being given that this driver originates from the FreeBSD version, and
** in order to keep synergy on both, any suggested enhancements and corrections
** received on Linux are automatically a potential candidate for the FreeBSD
** version.
**
** The original driver has been written for 386bsd and FreeBSD by
** Wolfgang Stanglmeier <wolf@cologne.de>
** Stefan Esser <se@mi.Uni-Koeln.de>
**
**-----------------------------------------------------------------------------
**
** Major contributions:
** --------------------
**
** NVRAM detection and reading.

** Added support for MIPS big endian systems.
