If second CPU is not enabled, CPC925 EDAC driver will spill out
warnings
about errors on second Processor Interface. Support masking that out,
by detecting at runtime which CPUs are present in device tree.
That doesn't quite work, there can be multiple CPUs per processor
interface.
You should be able to see which interfaces are enabled in some CPC925
register,
but maybe both _are_ enabled on your system (although one is not
connected),
which is causing the errors?
