of environment data (variable area); in general, we support the
following configurations:
-- CONFIG_BUILD_ENVCRC:
-
- Builds up envcrc with the target environment so that external utils
- may easily extract it and embed it in final U-Boot images.
-
- CONFIG_ENV_IS_IN_FLASH:
Define this if the environment is in flash memory.
