+ * SX8 hardware has a single message queue for all ATA ports.
+ * When this driver was written, the hardware (firmware?) would
+ * corrupt data eventually, if more than one request was outstanding.
+ * As one can imagine, having 8 ports bottlenecking on a single
+ * command hurts performance.
+ *
+ * Based on user reports, later versions of the hardware (firmware?)
+ * seem to be able to survive with more than one command queued.
+ *
+ * Therefore, we default to the safe option -- 1 command -- but
+ * allow the user to increase this.
+ *
+ * SX8 should be able to support up to ~60 queued commands (CARM_MAX_REQ),
+ * but problems seem to occur when you exceed ~30, even on newer hardware.

+ *
+ * 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.
