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.
