From ec877d633d0db3b40c28d2ef198313ab688cd3d4 Mon Sep 17 00:00:00 2001 From: Tracy Wu Date: Thu, 13 Jan 2022 21:53:02 +0800 Subject: mb/google/brya/variants/*: Add cpu pcie rp flags Along with commit f94405219c (soc/intel/alderlake: Hook up FSP-S CPU PCIe UPDs), we need to set cpu pcie rp flags in devicetree now. This CL is to add proper cpu pcie flags (PCIE_RP_LTR and PCIE_RP_AER) in all intel projects or system will be blocked at PKGC2R with root port LTR not enable. BUG=b:214009181 TEST=Build and DUT (Kano) can enter deeper PKGC state normally.
