From 8c6b44d00aca45edf69b35220ba4dce962c482f8 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Tue, 16 Jun 2009 06:01:58 +0900 Subject: sh: pci: Allow register_pci_controller() to handle overlapping regions. Some host controllers (such as SH7786) have overlapping regions that are fixed in hardware. The resource allocator does the right thing in managing this space already, so the conflict case is non-fatal.
