+ *
+ * Copyright 2005  Tejun Heo
+ *
+ * Based on preview driver from Silicon Image.
+ *
+ * NOTE: No NCQ/ATAPI support yet.  The preview driver didn't support
+ * NCQ nor ATAPI, and, unfortunately, I couldn't find out how to make
+ * those work.  Enabling those shouldn't be difficult.  Basic
+ * structure is all there (in libata-dev tree).  If you have any
+ * information about this hardware, please contact me or linux-ide.
+ * Info is needed on...
+ *
+ * - How to issue tagged commands and turn on sactive on issue accordingly.
+ * - Where to put an ATAPI command and how to tell the device to send it.
+ * - How to enable/use 64bit.
