PS2, Line 115: if SOC_INTEL_CSE_LITE_SKU
> When CSE Lite FW update should happen is board choice, i don't think this should part of SoC Kconfig list. This was discussed earlier with Googlers (Furquan) so we pushed it to board configuration.

Are you referring below change which selects CSE lite from mainboard ? as I mentioned/showed there instances already in SoC Kconfig where SOC_INTEL_CSE_LITE_SKU is used as decision point to select other config. For low maintenance it's better to keep it inside SoC (knowing there are 100+ boards to move the romstage section).

```
select SOC_INTEL_CSE_LITE_SKU
```

let me think if there are any better ways. I believe there are still some way.
