Something in your descripotion must be missing, or this change makes no sense to me. > #ifdef CONFIG_EXTRA_ENV_SETTINGS > CONFIG_EXTRA_ENV_SETTINGS > +#endif > +#ifdef CONFIG_USER_ENV_SETTINGS > + CONFIG_USER_ENV_SETTINGS > #endif What exactly is the difference between CONFIG_EXTRA_ENV_SETTINGS and CONFIG_USER_ENV_SETTINGS for you, i. e. what can you do with CONFIG_USER_ENV_SETTINGS that cannot be done in exatly the same way with CONFIG_EXTRA_ENV_SETTINGS? Maybe it would help if you include any code that is actually using this feature?
