Google Wilco Embedded Controller interface.
+ Note, the Wilco EC firmware is a modified version of Dell's
+ typical Latitude EC firmware, that implements a custom mailbox
+ protocol similar to the one used in the Chromium EC.
+
+ This particular EC firmware is not open source, just the
+ host-side interfaces (kernel and firmware drivers) are.
