But honestly, as of today we need to patch by reverting d5ba6188dfbf to use extlinux.conf with fitImage, so I'll vote to keep this solution and go forward and implement the change in the Poky/OE bootimg-partition bootloader partition generator with perhaps a check on the u-boot version.

I'd expect Yocto to have a local patch reverting this in their next release, where U-Boot would be bumped to something containing this commit, for example. By merging the patchset, we limit other possible implementations by adding one more logic we should then maintain for backward compatibility. Ack, you're right. Neil Cheers, Quentin

Yea no they will only break old u-boot with future extlinux.conf files with "FDT /fitImage", but without booting with fitImage as KERNEL is already broken since d5ba6188dfbf anyway. Neil
