Subject: [PATCH 17/17] powerpc: crypto: enable the PFO-based encryption device
Date: Wed, 21 Mar 2012 16:41:51 -0500 [thread overview]
Message-ID: <1332366111.3858.56.camel@key-ThinkPad-W510> (raw)
In-Reply-To: <1332365297.3858.5.camel@key-ThinkPad-W510>
This patch adds the cas bits to advertise support for the Platform
Facilities Option (PFO) based encryption accelerator device. The nx
device driver provides support for this hardware feature.
