For things like SoC, what I'd like is a way via #include or macros,
whatever, to layout in a part of the tree a standard block, and then, be
able to "overlay" on top of it.

I can see other uses for macros for things like making easier to build
interrupt-map properties for example, especially since most embedded
boards use standard swizzling
