This makes no sense to me.

Either the license is compatible, and the code can be included, or it
is not, then it cannot. In the latter case, the whole patch makes no
sense.

Please check for compatibility of licenses berfore resubmitting.

But so far there is no code (board support) in  U-Boot  to  use  this
feature, right? And it's not used by the Linux kernel either?

And your patch does not even enable support for it in the mkimage
tool, so you cannot even create images that use the feature?

How exactly is this code supposed to be used?

Frankly, if you are so short with flash you have a h/w dsign problem.
