This address might change if one moves ATF, might work to use CONFIG_K3_ATF_LOAD_ADDR? Not sure how you would get the end address as we don't really know ATF size..
I think this could be handled within binman IF CONFIG_K3_ATF_LOAD_ADDR and the ATF binary were not only A53/A72 inputs. But since it is, I don't see how that can be implemented.
