Distro Boot requires a U-Boot-specific script named boot.scr or boot.scr.uimg which contains boot commands to boot the system. The boot.cmd is such a file. Use mkimage to generate boot.scr or boot.scr.uimg from boot.cmd, and the command is: mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Distro Boot Script" -d boot.cmd boot.scr.uimg
QSPI in iMX8MM platform is only used to store bootloader and script so that we do not load image or .dtb file from QSPI as is shown in boot.cmd file.
The boot.cmd file is an example script and can be modified based on needs.
