- ** 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.
- ** Copyright (C) 1997 Richard Waltham <dormouse@farsrobt.demon.co.uk>
- **
- ** Added support for MIPS big endian systems.
