If only FIT images are enabled and loading the FIT image fails, spl_nor_load_image() should return an error instead of zero. Without this patch: >>SPL: board_init_r() spl_init Trying to boot from NOR Unsupported OS image.. Jumping nevertheless.. image entry point: 0x0 With patch: >>SPL: board_init_r() spl_init Trying to boot from NOR SPL: failed to boot from all boot devices (err=-6) .### ERROR ### Please RESET the board ### Signed-off-by: Mario Kicherer <dev@kicherer.org>
