The problem with these patches is that it prevents building all the
compatible device tree files for a board family. The default device
tree is just that - it is not the only one that can be used. A build
system can taken one of the output device tree files and package it
with U-Boot. If we don't build then, then that becomes impossible.

What is the purpose of these patches?

A better solution might be to add an option to list the files which
should be built. Then we gain control over this, if that is what you
are trying to achieve.

Simon
