From 5b93394318c04791c9b4edda7ff4af140427ed8a Mon Sep 17 00:00:00 2001 From: Anatolij Gustschin Date: Mon, 21 Jan 2013 23:50:27 +0000 Subject: [PATCH] mpc8xxx: fix DDR init value to use CONFIG_MEM_INIT_VALUE Configuring custom memory init value using CONFIG_MEM_INIT_VALUE in the board config file doesn't work and memory is always initialized to the value 0xdeadbeef. Only use this default value if a board doesn't define CONFIG_MEM_INIT_VALUE.
