PS20, Line 105: config CHROMEOS_ENABLE_ESOL
> So are you saying that the Kconfig only exists so that you can extract the `config` file from CBFS and check for it? I guess that's fine, but it is a very unusual use of Kconfig so you should definitely explain that in the `help` text here. If you just create an unused Kconfig and don't explain why you need it someone might go and delete it again.

valid point and adding a meaningful help text is always desirable. But with https://review.coreboot.org/c/coreboot/+/83769/comment/35b91b25_aaf1754c/ suggested changes, I believe this Kconfig is no more a unused Kconfig even in coreboot space.

also, you could change below code to use newly added Kconfig https://github.com/coreboot/coreboot/blob/main/src/soc/intel/alderlake/romst...

```
    if (!CONFIG(CHROMEOS_ENABLE_ESOL) ||
        !early_graphics_init()) {
    	timestamp_add_now(TS_ESOL_END);
    	return false;
    }

```
