But why should U-Boot need to be configured with image-specific
information, when we have well defined ways to store exactly that
needed information in the image itself? That would be a full step
backward.

Indeed - this is just one of the disadvatages and reasons why I reject
that new code.

If I find some time I will eventually re-review the IH_TYPE_*_REL
patches, and most probably apply them.

Best regards,
