This commit adds example scripts of boot.scr:
- bootzimg.cmd - check if dtb exists and boot zImage
- autoboot.cmd - check which image exists: Image.itb, zImage or uImage
and optionally load fdt file for u/zImage
The blank spaces are added to improve readability and can be removed
before use mkimage.
Required U-Boot environment variables: $boardname, $fdtfile, $console,
$mmcbootdev, $mmcbootpart, $mmcrootdev, $mmcrootpart, $rootfstype.
Making boot.scr from file.cmd:
mkimage -C none -A arm -T script -d file.cmd boot.scr
The Odroid XU3 default environment is ready for those boot scripts and
the right script can be loaded by DFU.
