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.

Thank for help!

We want to add UART functions on the board, it is superio to use eSPI interface,

How to recognize this interface in the system, there is currently modified bootblck.c and devicetree.cb, have other places to modify?
