Please stop planting statements on me that I did not make.
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.
