PS1, Line 236: enabling automatic detection
> Is there an option which lets the user to enable it explicitly or is it available implicit with Meteor Lake and newer?

not sure if you can access this [link](https://chromium-review.googlesource.com/c/chromiumos/overlays/chromiumos-ov...) where for CSE Lite FW update, we select two configs

```
# Management Engine FW update
CONFIG_SOC_INTEL_CSE_RW_UPDATE=y
CONFIG_SOC_INTEL_CSE_RW_VERSION="18.0.5.2107"
```

CONFIG_SOC_INTEL_CSE_RW_VERSION should match with the CSE FW blob otherwise it will cause boot loop with existing method. Now when we can land CB:80923 we don't need to explicitly mention the CSE RW FW version using yet another config. Therefore, we are planning to drop CONFIG_SOC_INTEL_CSE_RW_VERSION from all Meteor Lake device (which is so far the latest Intel SoC).

Here `automatic` refers to the CB:80923 which parse the CSE partition and retrieve CSE FW version without any static entry like CONFIG_SOC_INTEL_CSE_RW_VERSION
