The standard image generated by U-Boot on x86 is u-boot.rom. Add a separate image called image.bin for verified boot. This supports verification in TPL of which SPL/U-Boot to start, then jumping to the correct one, with SPL setting up the SDRAM and U-Boot proper providing the user interface if needed.
