Subject: [PATCH 24/28] mpc82xx: Remove a bunch of cruft that duplicates generic functionality.
Date: Mon, 17 Sep 2007 11:58:16 -0500	[thread overview]
Message-ID: <20070917165816.GX6563@loki.buserror.net> (raw)
In-Reply-To: <20070917165643.GA6545@loki.buserror.net>

m82xx_calibrate_decr(), mpc82xx_ads_show_cpuinfo(), and mpc82xx_halt() do
anything useful beyond what the generic code does.
