+ * Transport & Protocol Driver for In-System Design, Inc. ISD200 ASIC
+ *
+ * Current development and maintenance:
+ *   (C) 2001-2002 Björn Stenberg (bjorn@haxx.se)
+ *
+ * Developed with the assistance of:
+ *   (C) 2002 Alan Stern <stern@rowland.org>
+ *
+ * Initial work:
+ *   (C) 2000 In-System Design, Inc. (support@in-system.com)
+ *
+ * The ISD200 ASIC does not natively support ATA devices.  The chip
+ * does implement an interface, the ATA Command Block (ATACB) which provides
+ * a means of passing ATA commands and ATA register accesses to a device.
+ *
+ * History:
+ *
+ *  2002-10-19: Removed the specialized transfer routines.
+ *		(Alan Stern <stern@rowland.harvard.edu>)
+ *  2001-02-24: Removed lots of duplicate code and simplified the structure.
+ *	      (bjorn@haxx.se)
+ *  2002-01-16: Fixed endianness bug so it works on the ppc arch.
+ *	      (Luc Saillard <luc@saillard.org>)
+ *  2002-01-17: All bitfields removed.
