I concur with Gary here, this should be just:

config BR2_TARGET_UBOOT_FORMAT_FLASH_BIN
	bool "flash.bin"

and it should just trigger the build of the "flash.bin" target. The
dependency on i.MX firmware should be handled by the separate U-Boot
option I have proposed in reply to your PATCH 2/8.

Best regards,

Thomas
