Subject: [PATCH v3 17/17] powerpc: crypto: enable the PFO-based encryption device
Date: Thu, 12 Apr 2012 10:39:35 -0500 [thread overview]
Message-ID: <1334245175.18090.40.camel@key-ThinkPad-W510> (raw)
In-Reply-To: <1334242825.18090.4.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.
