Subject: [PATCH 5/6] DDR3: Repeat core timings as time values
Date: Wed, 10 Apr 2013 22:22:05 +0200	[thread overview]
Message-ID: <20130410222205.7c08cb85@endymion.delvare> (raw)
In-Reply-To: <20130410221330.213ca5be-R0o5gVi9kd7kN2dkZ6Wm7A@public.gmane.org>

DDR3: Repeat tCK, tAA, tRCD, tRP and tRAS values, so that they show up
no only as cycle counts but also absolute time values.
