From e13df08a2685345f12ae1ec1d99ea3f599d58360 Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Thu, 27 Feb 2020 13:56:10 +0000 Subject: env: remove callback.o for an SPL build 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.
