  21 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.
