I'm still not convinced to have this. As kernel followed by U-Boot we
thrust hardware more than something else.
One more layer in between is usually an additional point to be error-prone.

So, if something we may get directly from hardware, I consider better
to get it from there.

Of course, data structures can be left for sake of self-documentation.
