Sure. Even on real hardware there are gaps, and on the paravirt
platform we have loads of space. :-)
This does raise the question of what compatible the ccsr node should
have on the paravirt platform. Currently it's still labelled
"fsl,mpc8544-immr", which is clearly wrong. If we add CCSRBAR support,
should the paravirt platform have it as well? If so, what is the size
of CCSR on the paravirt platform?
