Description:
6+
Allow user space entities to trigger update of Slim
7+
Bootloader (SBL). This attribute normally has a value
8+
of 0 and userspace can signal SBL to update firmware,
9+
on next reboot, by writing a value of 1.
10+
There are two available states:
11+
* 0 -> Skip firmware update while rebooting
12+
* 1 -> Attempt firmware update on next reboot
