From 33e88c557b29c84c52039ba05993fa70fe62afe3 Mon Sep 17 00:00:00 2001 From: Jon Smirl Date: Sun, 22 Mar 2009 22:55:45 -0400 Subject: mpc5200: suppress printf until console initialized On boards which have the environment in eeprom, i2c_init() is called before the console and RAM are initialized. Suppress printfs until the console is initialized.
