From 1754f50b710194f886b6f2831803d8960171a14d Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Wed, 9 Jan 2008 10:25:46 +0100 Subject: [PATCH] ppc4xx: Add CFG_POST_ALT_WORD_ADDR to support non OCM POST WORD storage The privious 4xx POST implementation only supported storing the POST WORD in OCM. Since we need to reserve the OCM on LWMON5 for the logbuffer we need to store the POST WORD in some other non volatile location. This patch adds CFG_POST_ALT_WORD_ADDR to specify an address for such a location.
