From 623575e16cd55082ca36b57114a774f146b2c95b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?C=C3=A9dric=20Le=20Goater?= Date: Wed, 2 Mar 2022 06:51:39 +0100 Subject: [PATCH] ppc/pnv: Add model for POWER10 PHB5 PCIe Host bridge MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit PHB4 and PHB5 are very similar. Use the PHB4 models with some minor adjustements in a subclass for P10.
