The BootROM of MT7621 requires a image header for SPL to record its size and load address when booting from NAND. To create such an image, one can use the following command line: mkimage -T mtk_image -a 0x80200000 -e 0x80200000 -n "mt7621=1" -d u-boot-spl-ddr.bin u-boot-spl-ddr.img Reviewed-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com> Signed-off-by: Weijie Gao <weijie.gao@mediatek.com>
