Linux-2.6.12-rc2v2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+ *
+ * $Id: isd200.c,v 1.16 2002/04/22 03:39:43 mdharm Exp $
+ *
+ * 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.

+ *  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.
