The ChromeOS EC framework and drivers are written under the assumption that they will be running on a little-endian systems. Code which would be broken on big-endian can be found trivially. Some examples: cros_ec.c: suspend_params.sleep_timeout_ms = ec_dev->suspend_timeout_ms cros_ec_debugfs.c: resp->time_since_ec_boot_ms cros_ec_wdt.c: arg.req.reboot_timeout_sec = wdd->timeout Prevent the build for big-endian systems.
