- add DC395 SCSI driver

Documentation/scsi/dc395x.txt

+README file for the dc395x SCSI driver
+==========================================
+
+Status
+------
+The driver has been tested with CD-R and CD-R/W drives. These should
+be safe to use. Testing with hard disks has not been done to any
+great degree and caution should be exercised if you want to attempt
+to use this driver with hard disks.
+
+This is a 2.5 only driver. For a 2.4 driver please see the original
+driver (which this driver started from) at
+http://www.garloff.de/kurt/linux/dc395/
+
+Problems, questions and patches should be submitted to the mailing
+list. Details on the list, including archives, are available at
+http://lists.twibble.org/mailman/listinfo/dc395x/
+
+Parameters
+----------
+The driver uses the settings from the EEPROM set in the SCSI BIOS 
+setup. If there is no EEPROM, the driver uses default values.
+Both can be overriden by command line parameters (module or kernel
+parameters).
+
+The syntax is as follows:
+ dc395x = AdapterID, SpeedIdx, DevMode, AdaptMode, Tags, DelayReset
+
+AdapterID : Host Adapter SCSI ID
+SpeedIdx  : 0,1,...7 = 20,13.3,10,8,6.7,5.8,5,4 MHz               [ 7]
+DevMode   : Bitmap for Dev Cfg                                    [63]
+AdaptMode : Bitmap for Adapter Cfg                                [47]
+Tags      : The number of tags is 1<<x, if x has been specified   [ 4]
+DelayReset: The seconds to not accept commands after a SCSI Reset [ 1]
+
+DevMode bit definition:
+   Bit Val(hex) Val(dec)  Meaning
+   *0	 0x01	    1	  Parity check
+   *1	 0x02	    2	  Synchronous Negotiation
+   *2	 0x04	    4	  Disconnection
+   *3	 0x08	    8	  Send Start command on startup. (Not used)
+   *4	 0x10	   16	  Tagged Command Queueing
+   *5	 0x20	   32	  Wide Negotiation
+
+AdaptMode bit definition
+   Bit Val(hex) Val(dec)  Meaning
+   *0	 0x01	    1	  Support more than two drives. (Not used)
+   *1	 0x02	    2	  Use DOS compatible mapping for HDs greater than 1GB.
+   *2	 0x04	    4	  Reset SCSI Bus on startup.
+   *3	 0x08	    8	  Active Negation: Improves SCSI Bus noise immunity.
+    4	 0x10	   16	  Immediate return on BIOS seek command. (Not used)
+ (*)5	 0x20	   32	  Check for LUNs >= 1.
+
+If you set AdapterID to -1, the adapter will use conservative
+("safe") default settings instead; more precisely, dc395x=-1 is a
+shortcut for dc395x=7,4,9,15,2,10
+
+If you specify -2 for a value, it will be ignored. You don't need to
+specify all six parameters.

+License (GPL). Please read it, before using this driver. It should be
+included in your kernel sources and with your distribution. It carries the
