> Hi Mark,
It is possible, here is an example I have used on an NXP LS1043 board:
/dts-v1/;

/ {
         description = "ARM64 OpenWrt FIT (Flattened Image Tree)";
         #address-cells = <1>;

         images {
                 kernel at 1 {
                         description = "ARM64 OpenWrt Linux-4.4";
                         data = /incbin/("arch/arm64/boot/Image.gz");
                         type = "kernel";
                         arch = "arm64";
                         os = "linux";
                         compression = "gzip";
                         load = <0x80080000>;
                         entry = <0x80080000>;
                 };


                 ramdisk at 1 {
                         description = "ARM64 OpenWrt ramdisk";
                         data = /incbin/("root.squashfs");
                         type = "ramdisk";
                         arch = "arm64";
                         os = "linux";
                         compression = "gzip";
                 };


                 fdt at 1 {
                         description = "ARM64 OpenWrt device tree blob";
                         data = 
/incbin/("arch/arm64/boot/dts/freescale/fsl-ls1043a-rdb.dtb");
                         type = "flat_dt";
                         arch = "arm64";
                         compression = "none";
                         load = <0x90000000>;
                 };


         };

         configurations {
                 default = "config at 1";
                 config at 1 {
                         description = "OpenWrt";
                         kernel = "kernel at 1";
                         fdt = "fdt at 1";
                         ramdisk = "ramdisk at 1";
                 };
         };
};
