This EC is an incompatible variant of the typical Chrome OS embedded controller. It uses the same low-level communication and a similar protocol with some significant differences. The EC firmware does not support the same mailbox commands so it is not registered as a cros_ec device type. This commit exports the wilco_ec_mailbox() function so that other modules can use it to communicate with the EC.

If you say Y here, you get support for talking to the ChromeOS

Wilco EC over an eSPI bus. This uses a simple byte-level protocol

|
with a checksum.

To compile this driver as a module, choose M here: the

module will be called wilco_ec.
