Thanks for the overall review,

I will do a complete fixup of the constants and defines in a follow-up patchset,
since the already-merged code also needs a good cleanup.

I'll do a more complete refactoring to get rid of the _is_compatible() stuff
in a second time, it needs much more work to handle correctly the 4 SoC families.
