    env: remove callback.o for an SPL build · e13df08a
    Rasmus Villemoes authored
    env.h says this about about callback declarations (U_BOOT_ENV_CALLBACK):
    
     * For SPL these are silently dropped to reduce code size, since environment
     * callbacks are not supported with SPL.
    
    So env_callback_init() does a lot of work to not find anything in the
    guaranteed empty env_clbk list. Drop callback.o entirely from the link
    and stub out the only public function defined in callback.o. This cuts
    about 600 bytes from the SPL on my ppc build.
