8 ARM System Control and Management Interface (SCMI) protocol is a
9 set of operating system-independent software interfaces that are
10 used in system management. SCMI is extensible and currently provides
11 interfaces for: Discovery and self-description of the interfaces

29 This declares whether at least one SCMI facility is configured
