+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
