[coreboot] Change superio in "Bayley Bay FSP-based CRB"

[Zvi Vered]

Hello,

I have to port coreboot to a "Bay Trail" board (KONTRON).
I selected "Bayley Bay FSP-based CRB" as a reference.

In my board, the output of superiotool is:
Found Winbond W83627HF/F/HG/G (id=0x52, rev=0x41) at 0x2e

But the configuration of the reference board is:
*** Super I/O ***

How can I change it ?

I wish there was a basic configuration that could be easily modified.

Thank you,
Zvika

Hi Jose, All,

According to lspci I modified devicetree.cp copied from the "Bay
Trail" reference:

1. Should I add the devices at the end of the list marked with # in
domain 1.2.3 ?
2. How can I know to set 'on' or 'off' ?

Hello Zvika,
Add your device in Konfig and configure it under devicetree.
Look for examples and/or previous threads in this mail list.
Jose.
