 * @dd       Pointer to the driver data structure.

 * @start    First sector to read.

 * @nsect    Number of sectors to read.

 * @nents    Number of entries in scatter list for the read command.

 * @tag      The tag of this read command.

 * @callback Pointer to the function that should be called

 *	     when the read completes.

 *	None
