From dfc73e7acd9925b434a355eeeed86d44cb435f9c Mon Sep 17 00:00:00 2001 From: Sebastian Ott Date: Thu, 17 Apr 2014 19:46:15 +0200 Subject: [PATCH] PCI: Move Open Firmware devspec attribute to PCI common code Move the devspec OF attribute to PCI common code's set of device attributes since it's not architecture dependent. As a side effect microblaze and powerpc no longer need to use pcibios_add_platform_entries().
