Coreboot is a first-stage bootloader mostly used on x86 devices as an alternative to UEFI. Coreboot runs in 32-bit mode. U-Boot currently supports booting from coreboot as a second-stage bootloader, also in 32-bit mode. However it is useful to be able to run U-Boot in 64-bit mode. To do this we can have a 32-bit SPL which switches over the CPU and jumps to a 64-bit U-Boot proper. Add a new 'coreboot64' board for running 64-bit U-Boot from coreboot. This uses binman to create an image with a 32-bit SPL and a 64-bit U-Boot. This allows running 64-bit EFI images on x86, for example, without needing a native U-Boot port for a board.
