ext4load seems to be available on the u-boot command line.

After loading boot.scr, don't we need the "source" command to work? "source" does not seem to be configured in the pre-installed u-boot.

Also, to create boot.scr we need mkimage. I wonder if modern Debian u-boot-tools' mkimage will create a boot.scr that is compatible with the pre-installed u-boot (remember that I couldn't build the old u-boot with the new compilers).

I guess, I can just load the image with ext4load instead of fatload. Not sure why the original instructions required two partitions then..
