Well, flash-kernel could be taught how to parse .dtb files to get the
compatibility strings out of them, rather than use filenames.
It might still be early enough to give distributions some guidelines
about what DT folks consider ABI and what is not. How they should find
a fitting .dtb file and how they should not.
