[PATCH] powerpc/powernv/prd: Validate whether address to be mapped is part of system RAM

Hi Vasant,

It sure sounds like the issue - someone has represented a range that
should be mapped by HBRT, but isn't appropriate for mapping by HBRT.

OK. How about we just don't do that?

It sounds like we're just trying to work around an invalid
representation of the mappings.

Cheers,
