From 93aef2a789778e7ec787179fc9b34ca4885a5ef3 Mon Sep 17 00:00:00 2001 From: Gavin Shan Date: Fri, 22 Nov 2013 16:28:45 +0800 Subject: [PATCH] powerpc/powernv: Move PHB-diag dump functions around Prior to the completion of PCI enumeration, we actively detects EEH errors on PCI config cycles and dump PHB diag-data if necessary. The EEH backend also dumps PHB diag-data in case of frozen PE or fenced PHB. However, we are using different functions to dump the PHB diag-data for those 2 cases. The patch merges the functions for dumping PHB diag-data to one so that we can avoid duplicate code. Also, we never dump PHB3 diag-data during PCI config cycles with frozen PE. The patch fixes it as well.
