From dde265f5a22c7b75a2d502a66ae706e6b1e04561 Mon Sep 17 00:00:00 2001 From: Felix Held Date: Tue, 30 Jan 2024 15:40:53 +0100 Subject: soc/amd/common/data_fabric/domain: introduce add_pci_cfg_resources Since reporting the PCI ECAM MMCONF MMIO region and the IO ports for the legacy PCI config space access is needed on all AMD SoCs, implement a common add_pci_cfg_resources function that reports both and gets called from amd_pci_domain_read_resources and don't report those in the SoC- specific code any more. The only functional change is that on Genoa now the IO ports used for the legacy PCI config space access get reserved.
