From 21fd21f59082c2538883a280e7f0e9b374cf6cec Mon Sep 17 00:00:00 2001 From: Gavin Shan Date: Thu, 20 Jun 2013 13:20:57 +0800 Subject: powerpc/eeh: EEH post initialization operation The patch adds new EEH operation post_init. It's used to notify the platform that EEH core has completed the EEH probe. By that, PowerNV platform starts to use the services supplied by EEH functionality.
