From 709389b654de05fd6035656f5e082ba1757807b3 Mon Sep 17 00:00:00 2001 From: York Sun Date: Fri, 17 Aug 2012 08:20:26 +0000 Subject: powerpc/mpc8xxx: fix core id for multicore booting For the cores with multiple threads, we need to figure out which physical core a thread belongs. To match the core ids, update PIR registers and spin tables.
