When CTRL+C is pressed interrupt bootmenu and jump into U-Boot console. As the last entry in bootmenu is always U-Boot console just choose the last entry when CTRL+C is pressed.
It is useful when bootmenu is part of boot process and you want to interrupt boot process by scripts which control U-Boot (serial) console.
