@@ -2305,11 +2305,6 @@ The following definitions that deal with the placement and management
 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.
