Subject: [PATCH 07/27] powerpc/eeh: EEH post initialization operation
Date: Sat, 15 Jun 2013 17:02:58 +0800 [thread overview]
Message-ID: <1371286998-2842-8-git-send-email-shangw@linux.vnet.ibm.com> (raw)
In-Reply-To: <1371286998-2842-1-git-send-email-shangw@linux.vnet.ibm.com>
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.
