So this means that we can use /boot/extlinux/extlinux.conf instead of
boot.scr as it is easier to work with. Else you would need the boot.scr
to conform to u-boot's distro boot requirements.

It'd be better to check that stuff with packan-key or gpg.

I've quoted that script below:

I did a quick look, and bootpart is probably not part of the u-boot
environment anymore.

Also it seems that we don't have compatibility with old boot scripts:
$ grep CONFIG_OLD_SUNXI_KERNEL_COMPAT .config
# CONFIG_OLD_SUNXI_KERNEL_COMPAT is not set

So that probably fails because of the bootpart. The addresses look
compliant, devtype and devnum probably works as they are widely used,
but I didn't see them mentioned in doc/README.distro.

There is no /boot/uImage + the bootpart probably fails too here, it
would also need the devicetree and so on to work.

Try to rm mnt/boot/boot.scr, because u-boot probably tries that script
first, before trying /boot/extlinux/extlinux.conf.
