+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.
