Current behavior is to try to load uImage from mmc first, if it fails
then it tries tftp.

Isn't this 'exit' that you introduced preventing tftp transfer in the
case of mmc fail?

Also, can you confirm that your patchset works in the following cases:

1. Loading a non-dt kernel via mmc
2. Loading a dt kernel via mmc
3. Loading a non-dt kernel via tftp
4. Loading a dt kernel via tftp
