That's certainly not what I've seen going on.  Each implementation is
customised to the needs of the SoC it's running on - OMAP has a complex
implementation, whereas simpler SoCs have a more simple implementation.

That's an entirely reasonable state of affairs - those who need complexity
are able to have it, whereas those who don't need complexity don't have
to be lumbered with it.

It's a long way from a "cut and copy" situation you're trying to suggest
it is.  Certainly on ARM, your viewpoint does not hold.
