Description: Display fw status registers content
22
+
23
+
The ME FW writes its status information into fw status
24
+
registers for BIOS and OS to monitor fw health.
25
+
26
+
The register contains running state, power management
27
+
state, error codes, and others. The way the registers
28
+
are decoded depends on PCH or SoC generation.
29
+
Also number of registers varies between 1 and 6
30
+
depending on generation.
