Otherwise non-ChromeOS samsung devices, like the odroid boards, are stuck in a bootloop if CONFIG_CROS_EC is not enabled:
<...> MMC: SAMSUNG SDHCI: 2, EXYNOS DWMMC: 0 Loading Environment from MMC... *** Warning - bad CRC, using default environment
cros-ec communications failure -96
Please reset with Power+Refresh
Cannot init cros-ec device resetting ...
Issue started after commit e44d7e73fe0d ("dm: core: Switch uclass_*_device_err to use uclass_*_device_check").
