From e4e6db5283f775e44879246c6c93cb2462cf742f Mon Sep 17 00:00:00 2001 From: Daniel Henrique Barboza Date: Fri, 24 Jun 2022 05:49:11 -0300 Subject: ppc/pnv: add PnvPHB base/proxy device The PnvPHB device is going to be the base device for all other powernv PHBs. It consists of a device that has the same user API as the other PHB, namely being a PCIHostBridge and having chip-id and index properties. It also has a 'backend' pointer that will be initialized with the PHB implementation that the device is going to use. The initialization of the PHB backend is done by checking the PHB version via a 'version' attribute that can be set via a global machine property. The 'version' field will be used to make adjustments based on the running version, e.g. PHB3 uses a 'chip' reference while PHB4 uses 'pec'. To init the PnvPHB bus we'll rely on helpers for each version. The version 3 helper is already added (pnv_phb3_bus_init), the PHB4 helper will be added later on. For now let's add the basic logic of the PnvPHB object, which consists mostly of pnv_phb_realize() doing all the work of checking the phb->version set, initializing the proper backend, passing through its attributes to the chosen backend, finalizing the backend realize and adding a root port in the end.
