From b0c568de32bad5dc19722ba90ebe07e358675e51 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Thu, 15 Jan 2015 16:21:49 -0600 Subject: frv/PCI: Clip bridge windows to fit in upstream windows Every PCI-PCI bridge window should fit inside an upstream bridge window because orphaned address space is unreachable from the primary side of the upstream bridge. If we inherit invalid bridge windows that overlap an upstream window from firmware, clip them to fit and update the bridge accordingly.
