  *  NV-specific details such as register offsets, SATA phy location,
  *  hotplug info, etc.
  *
- *  0.10
- *     - Fixed spurious interrupts issue seen with the Maxtor 6H500F0 500GB
- *       drive.  Also made the check_hotplug() callbacks return whether there
- *       was a hotplug interrupt or not.  This was not the source of the
- *       spurious interrupts, but is the right thing to do anyway.
- *
- *  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.
