| 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. |
