Binman might be first priority boot image to be used but not mandatory
for all cases. Some boards use SPL or TPL+SPL and U-Boot proper
separately in order to change the SPL or TPL+SPL for supporting Multi
DTB on a variety of boards without updating U-Boot proper from the
factory. idbloader.img can be a legacy image name but it is derived
from rockchip and many boards are already used it and it is simply
recognized by rockchip board vendors.

Thanks,
