+	  The old configuration infrastructure (= mkconfig + boards.cfg)
+	  provided the extra options field. It you have something like
+	  "HAS_BAR,BAZ=64", the optional options
+	    #define CONFIG_HAS
+	    #define CONFIG_BAZ	64
+	  will be defined in include/config.h.
+	  This option was prepared for the smooth migration from the old
+	  configuration to Kconfig. Since this option will be removed sometime,
+	  new boards should not use this option.
