+2 Current Version : 00.00.04.31-rc1
+3 Older Version   : 00.00.04.17.1-rc1
+
+1.      Add the Online Controller Reset (OCR) to the Driver.
+        OCR is the new feature for megaraid_sas driver which
+        will allow the fw to do the chip reset which will not
+        affact the OS behavious.
+
+        To add the OCR support, driver need to do:
+                a). reset the controller chips -- Xscale and Gen2 which
+                will change the function calls and add the reset function
+                related to this two chips.
+
+                b). during the reset, driver will store the pending cmds
+                which not returned by FW to driver's pending queue.  Driver
+                will re-issue those pending cmds again to FW after the OCR
+                finished.
+
+                c). In driver's timeout routine, driver will report to
+                OS as reset. Also driver's queue routine will block the
+                cmds until the OCR finished.
+
+                d). in Driver's ISR routine, if driver get the FW state as
+                state change, FW in Failure status and FW support online controller
+                reset (OCR), driver will start to do the controller reset.
+
+                e). In driver's IOCTL routine, the application cmds will wait for the
+                OCR to finish, then issue the cmds to FW.
+
+                f). Before driver kill adapter, driver will do last chance of
+                OCR to see if driver can bring back the FW.
+
+2.      Add the support update flag to the driver to tell LSI megaraid_sas
+        application which driver will support the device update.  So application
+        will not need to do the device update after application add/del the device
+        from the system.
+3.      In driver's timeout routine, driver will do three time reset if fw is in
+        failed state.  Driver will kill adapter if can't bring back FW after the
+        this three times reset.
+4.      Add the input parameter max_sectors to 1MB support to our GEN2 controller.
+        customer can use the input paramenter max_sectors to add 1MB support to GEN2
+        controller.
