The Kernel Image and DTB files are supposed to be picked from the rootfs of the SD Card, this fails in legacy boot flow because bootpart is set to 1:1. Fix it.
and where is that rule defined?
Production boards ship with Kernel Image and DTB's in the 1st fat partition..
Besides, u-boot should scan for extlinux.conf on "any" partition.
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.
