+Description: Display fw status registers content
+
+ The ME FW writes its status information into fw status
+ registers for BIOS and OS to monitor fw health.
+
+ The register contains running state, power management
+ state, error codes, and others. The way the registers
+ are decoded depends on PCH or SoC generation.
+ Also number of registers varies between 1 and 6
+ depending on generation.
