From ba24e2ac3bdb5c489f3c787e7542b6474c4d65c6 Mon Sep 17 00:00:00 2001
From: Gerald Van Baren <vanbaren@cideas.com>
Date: Wed, 25 Apr 2007 21:24:27 -0400
Subject: [PATCH] Improve error messages, more informative.

Print more than the raw libfdt error message strings.  This is especially
useful for cluing in the user when the bootm command aborts due to
blob problems.
