[coreboot] Re: How to add superIO support with serial port logic enabled ?

[Naresh G. Solanki]

Findout which superio chip your board has.
There are some superio already supported. Check path src/superio/
If a match is found then select that in the kconfig of your mainboard &
also update devicetree.cb to configure it as per the board you have.
