PowerPC does something with the powerpc equivalent of the PVR.
We should just do what they do...

In the long term, this may be true.  In the short term:
1) dtb size is not the key problem
2) making sure that everything works is a key problem.
3) The code that generates the dts should be as simple as possible,
so that we can easily document what it does.

In the long term, I'm all for optimizing the device tree that gets
built,
assuming that it appears to be a problem in real systems.
