From 4ff62e1c7f5263427e742069235d94ba1336960d Mon Sep 17 00:00:00 2001 From: Scott Wood Date: Mon, 27 Aug 2007 16:56:43 -0500 Subject: [PATCH] [POWERPC] mpc82xx: Remove a bunch of cruft that duplicates generic functionality. m82xx_calibrate_decr(), mpc82xx_ads_show_cpuinfo(), and mpc82xx_halt() do anything useful beyond what the generic code does.
