From 51abee64eee0186634858d1e6f91a65969c90125 Mon Sep 17 00:00:00 2001 From: Laurentiu TUDOR Date: Wed, 23 Oct 2013 15:20:45 +0300 Subject: [PATCH] powerpc/85xx: fix broken cpu "clock-frequency" property When indexing freqProcessor[] we use the first value in the cpu's "reg" property, which on new e6500 cores IDs the threads. But freqProcessor[] should be indexed with a core index so, when fixing "the clock-frequency" cpu node property, access the freqProcessor[] with the core index derived from the "reg' property. If we don't do this, last half of the "cpu" nodes will have broken "clock-frequency" values.
