I can see where you come from, and I agree on the above points when it
comes to stdboot.
However when a user wishes to use legacy boot, and in the case there
isn't extlinux.conf in such a case u-boot will rely on information in
the env file (please correct me if my understanding is wrong).

The env file says:
bootdir=/boot

Thus u-boot ends up looking for Image and dtb in /boot/Image under BOOT
partition, and ultimately fails, because the /boot/Image path is
generally found inside the root partition ie. 1:2

The idea of this patch is to keep support for such legacy boot alive, if
you feel there's another way to do this feel free to suggest.
