From dff22d2054b5dbb1889f20c03959dd0c494fab8c Mon Sep 17 00:00:00 2001 From: Lorenzo Pieralisi Date: Thu, 9 Jul 2015 11:59:16 +0100 Subject: PCI: Call pci_read_bridge_bases() from core instead of arch code When we scan a PCI bus, we read PCI-PCI bridge window registers with pci_read_bridge_bases() so we can validate the resource hierarchy. Most architectures call pci_read_bridge_bases() from pcibios_fixup_bus(), but PCI-PCI bridges are not arch-specific, so this doesn't need to be in arch-specific code. Call pci_read_bridge_bases() directly from the PCI core instead of from arch code. For alpha and mips, we now call pci_read_bridge_bases() always; previously we only called it if PCI_PROBE_ONLY was set.
