From 1f5bef30cf6c66f097ea5dfc580a41924df888d1 Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Tue, 8 Jun 2010 07:48:09 -0600 Subject: of/address: merge of_address_to_resource() Merge common code between PowerPC and Microblaze. This patch also moves the prototype of pci_address_to_pio() out of pci-bridge.h and into prom.h because the only user of pci_address_to_pio() is of_address_to_resource().
