* - NG (Next Generation) mode is default mode from V4.0. It's easy to settings,
* only defined the ENV_AREA_SIZE.
* - The LEGACY mode has been DEPRECATED. It is NOT RECOMMENDED to continue
* using. Beacuse it will use ram to buffer the ENV and spend more flash erase
* times. If you want use it please using the V3.X version.
