+Description:
+		Allow user space entities to trigger update of Slim
+		Bootloader (SBL). This attribute normally has a value
+		of 0 and userspace can signal SBL to update firmware,
+		on next reboot, by writing a value of 1.
+		There are two available states:
+		    * 0 -> Skip firmware update while rebooting
+		    * 1 -> Attempt firmware update on next reboot
