+ * 04-30-07 02.00.00 Corresponds to Fusion-MPT MPI Specification Rev A.
+ * 06-04-07 02.00.01 In IOCFacts Reply structure, renamed MaxDevices to
+ * MaxTargets.
+ * Added TotalImageSize field to FWDownload Request.
+ * Added reserved words to FWUpload Request.
+ * 06-26-07 02.00.02 Added IR Configuration Change List Event.
+ * 08-31-07 02.00.03 Removed SystemReplyQueueDepth field from the IOCInit
+ * request and replaced it with
+ * ReplyDescriptorPostQueueDepth and ReplyFreeQueueDepth.
+ * Replaced the MinReplyQueueDepth field of the IOCFacts
+ * reply with MaxReplyDescriptorPostQueueDepth.
+ * Added MPI2_RDPQ_DEPTH_MIN define to specify the minimum
+ * depth for the Reply Descriptor Post Queue.
+ * Added SASAddress field to Initiator Device Table
+ * Overflow Event data.
+ * 10-31-07 02.00.04 Added ReasonCode MPI2_EVENT_SAS_INIT_RC_NOT_RESPONDING
+ * for SAS Initiator Device Status Change Event data.
+ * Modified Reason Code defines for SAS Topology Change
+ * List Event data, including adding a bit for PHY Vacant
+ * status, and adding a mask for the Reason Code.
+ * Added define for
+ * MPI2_EVENT_SAS_TOPO_ES_DELAY_NOT_RESPONDING.
+ * Added define for MPI2_EXT_IMAGE_TYPE_MEGARAID.
+ * 12-18-07 02.00.05 Added Boot Status defines for the IOCExceptions field of
+ * the IOCFacts Reply.
+ * Removed MPI2_IOCFACTS_CAPABILITY_EXTENDED_BUFFER define.
+ * Moved MPI2_VERSION_UNION to mpi2.h.
+ * Changed MPI2_EVENT_NOTIFICATION_REQUEST to use masks
+ * instead of enables, and added SASBroadcastPrimitiveMasks
+ * field.
+ * Added Log Entry Added Event and related structure.
+ * 02-29-08 02.00.06 Added define MPI2_IOCFACTS_CAPABILITY_INTEGRATED_RAID.
+ * Removed define MPI2_IOCFACTS_PROTOCOL_SMP_TARGET.
+ * Added MaxVolumes and MaxPersistentEntries fields to

+ * Removed MPI2_PORTENABLE_FLAGS_ENABLE_SINGLE_PORT.
+ * 03-03-08 02.00.07 Fixed MPI2_FW_IMAGE_HEADER by changing Reserved26 to
+ * a U16 (from a U32).
+ * Removed extra 's' from EventMasks name.
+ * 06-27-08 02.00.08 Fixed an offset in a comment.
+ * 10-02-08 02.00.09 Removed SystemReplyFrameSize from MPI2_IOC_INIT_REQUEST.
+ * Removed CurReplyFrameSize from MPI2_IOC_FACTS_REPLY and
+ * renamed MinReplyFrameSize to ReplyFrameSize.
+ * Added MPI2_IOCFACTS_EXCEPT_IR_FOREIGN_CONFIG_MAX.
+ * Added two new RAIDOperation values for Integrated RAID
+ * Operations Status Event data.
+ * Added four new IR Configuration Change List Event data
+ * ReasonCode values.

+ * Change Event data.
+ * Added three new DiscoveryStatus bits for the SAS
+ * Discovery event data.
+ * Added Multiplexing Status Change bit to the PhyStatus
+ * field of the SAS Topology Change List event data.
+ * Removed define for MPI2_INIT_IMAGE_BOOTFLAGS_XMEMCOPY.
+ * BootFlags are now product-specific.
+ * Added defines for the indivdual signature bytes
+ * for MPI2_INIT_IMAGE_FOOTER.
+ * 01-19-09 02.00.10 Added MPI2_IOCFACTS_CAPABILITY_EVENT_REPLAY define.
