Now that BootROM always loads main U-Boot binary, the legacy 64-byte header is not used anymore. BootROM uses only kwbimage v1 headers where all necessary information about how to load and execute SPL / U-Boot is present.
Remove this 64-byte header by putting u-boot.bin binary (instead of u-boot.img) into kwbimage v1 and let BootROM to load U-Boot directly at its execution address.
