menuconfig MCHP_MEC_UNSIGNED_HEADER
	bool "Create an unsigned output binary with MCHP MEC binary header"
	help
	  On Microchip MEC series chip, the ROM code loads firmware image from flash
	  to RAM using a TAG to locate a Header which specifies the location and
	  size of the firmware image. Enable this to invoke the mec_spi_gen tool
	  which generates an SPI image with TAG, Header, and firmware binary. This
	  tool does not produce a signed image which can be authenticated by the
	  Boot-ROM. Use the full Microchip SPI image generator program for
	  authentication and all other Boot-ROM loader features. Refer to the MCHP
	  EVB boards for an example.
