From 34557b7504778e32b166cf46c6f774086124e845 Mon Sep 17 00:00:00 2001 From: Pali Rohár Date: Sat, 28 Jan 2023 14:34:58 +0100 Subject: powerpc/pci: Enable PPC_PCI_BUS_NUM_DOMAIN_DEPENDENT by default MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit It makes sense to enable CONFIG_PPC_PCI_BUS_NUM_DOMAIN_DEPENDENT by default (when possible by dependencies) to take advantages of all 256 PCI buses on each PCI domain, like it is already on all other kernel architectures.
