I think this is expected as you are trying to enable CONFIG_OF_BOARD_SETUP but
AM64 platform does not implement ft_board_setup.

Platforms need to implement ft_board_setup for platform specific knobs (for
e.g. simplefb for splash etc) if using CONFIG_OF_BOARD_SETUP as per below
snippet in boot/image-fdt.c :

        if (IS_ENABLED(CONFIG_OF_BOARD_SETUP)) {

                const char *skip_board_fixup;



                skip_board_fixup = env_get("skip_board_fixup");

                if (skip_board_fixup && ((int)simple_strtol(skip_board_fixup,
NULL, 10) == 1)) {
                        printf("skip board fdt fixup\n");

                } else {

                        fdt_ret = ft_board_setup(blob, gd->bd);

                        if (fdt_ret) {

                                printf("ERROR: board-specific fdt fixup
failed: %s\n",
                                       fdt_strerror(fdt_ret));

                                goto err;

                        }

                }

        }
