As suggested in commit028abfd9b1("imx8mm-evk: Generate a single bootable flash.bin again") for imx8mm_evk, it is possible to produce single bootable image via binman. This restores the original behavior in distros, where only one boot container is used to create target image. Perform similar adaptions in order to provide single bootable image for imx8mn-ddr4-evk derivate. Update documentation to drop additional step of copying u-boot.itb Fixes:353dfe4b43("imx8mn-ddr4-evk: switch to use binman") Signed-off-by: Andrey Zhizhikin <andrey.zhizhikin@leica-geosystems.com> Reviewed-by: Fabio Estevam <festevam@gmail.com>
