+	  the environment found in the environment sector is
+	  invalid. This option sets the barebox Kconfig option
+	  CONFIG_DEFAULT_ENVIRONMENT_PATH to the specified path. This
+	  way it is possible to use Buildroot variables like
+	  BR2_EXTERNAL, TOPDIR etc. to refer to the custom
+	  environment.
