I might be too late to say this but the SEQ thing looks ugly to me.
Maybe there could be some generic control-flow-like nodes that could
generate and insert things in their own place. If it makes sense, I'm
imagining something like:

    fit {
        images {
            __for__ {
                for,variable = "name";
                for,in-args = "of-list";

                fdt-#name {
                    description = "fdt-$name.dtb";
                    type = "flat_dt";
                    compression = "none";
                };
            };
        };

        configurations {
            __for__ {
                for,variable = "name"
                for,in-args = "of-list";

                __if__ {
                    if,arg-equals = "default-dt", "$name";
                    default = "config-#name";
                };

                config-#name {
                    description = "conf-$name.dtb";
                    fdt = "fdt-#name";
                };
            };
        };
    };
