ppc/pnv: introduce a new dt_populate() operation to the chip model
The POWER9 and POWER8 processors have a different set of devices and a different device tree layout. Signed-off-by: Cédric Le Goater <clg@kaod.org> Message-Id: <20190306085032.15744-8-clg@kaod.org> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
