dtc: Empty ranges property: #cells-size warning

[Stefan Roese]

Hi,

when changing #cells-size from 1 to 2 in the root node (to support >= 4GB of 
RAM in katmai.dts) I get the following warning:

Warning (ranges_format): /plb has empty "ranges" property but its #size-cells 
(1) differs from / (2)

I could change #cells-size to 2 in the plb node as well. But this not really 
what I want, because of it's child nodes.

So my questions is: How can I solve this problem? Perhaps this warning should 
be removed from dtc?

Thanks.

Cheers,
Stefan
