[coreboot] Porting a board, how to get the overcurrent pin mapping for QM370?

[Jose Trujillo]

Hello Ladies and Gentlemen:

I am trying to do the porting of a computer module based on Intel CoffeeLake/QM370.
I don't have the schematics.
I was trying to find out how to extract/dump the overcurrent pin mapping from the system, but I was unable to find this information.
I need this configuration to correctly set the USB configuration in the devicetree.cb.

In older systems previous to Skylake this information was in the RCBA (dumped by inteltool), but there is no RCBA in newer chipsets.

Anyone can help me in providing the steps?

Thank you,
Jose Trujillo.
