Sorry, but that's what I believe you meant. If you didn't mean that,
well then let's clear this up, and the rest of the conversation will be
a lot simpler:

I believe that for building the *.dts in U-Boot we should simply require
the user to have a version of dtc that supports the recently added
features such as:

* -i directive.
* Ability to parse the output of cpp well (e.g. #line directives, emit
useful error/warning messages in this case).
* Cell expression support.

Those are all present in the latest git repo for dtc.

If we do that, then we won't need any conditional logic in the U-Boot
makefiles. At least parts of Simon's patch won't be necessary.

I'm quite happy to achieve this requirement by having the user install
that dtc into the $PATH prior to running any U-Boot make, either
manually or via distro packages once they're available.

It is my understanding that you object to requiring such a new version
of dtc, irrespective of the means by which it's provided. If this is not
true, then please do let me know; it would vastly simplify matters.
