> > I am implementing the sku_id defined in https://github. […]
> > in that case, can you implement sku_id() inside cros_ec file itself so you don't need to implement per board basic ? and use some smart method to call into ADC PIN when CONFIG_SKUID_VIA_CHROMEEC vs CONFIG_SKUID_VIA_ADC_PIN.

IIUC, cros_ec hosts the ec<->host APIs, Since sku_id is specific to mainboards and allows to define mainboard specific SKU ID mechanisms, this can be implemented per board.

Agree, updated the commit, PTAL.
