|

*
|
|
* Based loosely on aha1542.c which is
|
|
* Copyright (C) 1992 Tommy Thorn and
|
|
* Modified by Eric Youngdale
|
|
*
|
|
* This file is aha1740.c, written and
|
|
* Copyright (C) 1992,1993 Brad McLean
|
|
* brad@saturn.gaylord.com or brad@bradpc.gaylord.com.
|
|
*
|
|
* Modifications to makecode and queuecommand
|
|
* for proper handling of multiple devices courteously
|
|
* provided by Michael Weller, March, 1993
|
|
*
|
|
* Multiple adapter support, extended translation detection,
|
|
* update to current scsi subsystem changes, proc fs support,
|
|
* working (!) module support based on patches from Andreas Arens,
|
|
* by Andreas Degert <ad@papyrus.hamburg.com>, 2/1997
|
|
*
|
|
* aha1740_makecode may still need even more work
|
|
* if it doesn't work for your devices, take a look.
|
|
*
|
|
* Reworked for new_eh and new locking by Alan Cox <alan@lxorguk.ukuu.org.uk>
|
|
*
|
|
* Converted to EISA and generic DMA APIs by Marc Zyngier
|
|
* <maz@wild-wind.fr.eu.org>, 4/2003.
|
|
*
|
|
* Shared interrupt support added by Rask Ingemann Lambertsen
|
|
* <rask@sygehus.dk>, 10/2003
|
|
*
|
|
* For the avoidance of doubt the "preferred form" of this code is one which
|
|
* is in an open non patent encumbered format. Where cryptographic key signing
|
|
* forms part of the process of creating an executable the information
|
|
* including keys needed to generate an equivalently functional executable
|
|
* are deemed to be part of the source code.
