The released Linux boot image header in v5.3 is different from the one present in U-Boot. Align the header with the new version. The changes in Linux are backward compatible. Previous U-Boot releases with older header will continue to work as well. As v5.3 kernel is the first one to support image header, there is no compatibility issue between new U-Boot (with this patch) and older kernel.
