+ depends on !SPL_BUILD
+ help
+ 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.
