build/roms: Support using U-Boot as a coreboot payload
This enables embedding U-Boot into the coreboot roms as the payload. For now, the ELF file generated by enabling CONFIG_REMAKE_ELF is used, which includes the U-Boot binary and the board-specific device-tree file. It might be better to use the FIT payload support for U-Boot, but that was reportedly broken and is not tested yet. Coreboot boards can specify payload_uboot="y" in their board.cfg to enable building a rom with U-Boot as the payload, which is built from the U-Boot board with the same name. Boards can further specify a uboot_config option, to choose which board-specific config file U-Boot should be built with. Signed-off-by: Alper Nebi Yasak <alpernebiyasak@gmail.com>
