- *
- * 0.09
- * - Fixed bug introduced by 0.08's MCP51 and MCP55 support.
- *
- * 0.08
- * - Added support for MCP51 and MCP55.
- *
- * 0.07
- * - Added support for RAID class code.
- *
- * 0.06
- * - Added generic SATA support by using a pci_device_id that filters on
- * the IDE storage class code.
- *
- * 0.03
- * - Fixed a bug where the hotplug handlers for non-CK804/MCP04 were using
- * mmio_base, which is only set for the CK804/MCP04 case.
- *
- * 0.02
- * - Added support for CK804 SATA controller.
- *
- * 0.01
- * - Initial revision.
