[coreboot] ec/google/wilco: Details on EC firmware

[Paul Menzel]

Dear coreboot folks,

Some Google Chromebooks come with a Google Wilco EC (EC_GOOGLE_WILCO) 
instead of Google Chrome EC. coreboot implements the interface for the 
Google Wilco EC.

Unfortunately, I was unable to find more details on the firmware. 
Phoronix claims is “open-source firmware” [1].

It’d be great if somebody could provide some details.

Kind regards,

Paul
