From c9c11d751e4242cf29c3c3c290d971f6d0cb1d15 Mon Sep 17 00:00:00 2001 From: Adam Graham Date: Wed, 8 Oct 2008 10:13:19 -0700 Subject: ppc4xx: Add routine to retrieve CPU number Provide a weak defined routine to retrieve the CPU number for reference boards that have multiple CPU's. Default behavior is the existing single CPU print output. Reference boards with multiple CPU's need to provide a board specific routine. See board/amcc/arches/arches.c for an example.
