		Uses a MCUboot boot banner instead of the default zephyr one, which will output the
		MCUboot name and version, followed by the zephyr name and version.

		For example:

		* Booting MCUboot v2.0.0-72-g8c0e36c88663 *
		* Using Zephyr OS build v3.6.0-2607-gd0be2010c31f *

		config BOOT_BANNER_STRING
		default "Using Zephyr OS build" if MCUBOOT_BOOT_BANNER

		endmenu
