From ec98e9ab6f2475ff57c12d069e78b90548c0f60e Mon Sep 17 00:00:00 2001 From: Minghuan Lian Date: Tue, 23 Sep 2014 22:28:56 +0800 Subject: [PATCH] PCI: designware: Fix configuration base address when using 'reg' The code has calculated cfg0_base and cfg1_base when parsing 'reg' or 'ranges' property of PCI DTS node, so remove duplicate calculation. When using 'reg', resource cfg is not used, so this code computed an incorrect configuration base.
