From 9a4daad0a35eb5143037eea9f786a3e9d672bdd6 Mon Sep 17 00:00:00 2001 From: Marian Balakowicz Date: Fri, 29 Feb 2008 14:58:34 +0100 Subject: [new uImage] Update naming convention for bootm/uImage related code This patch introduces the following prefix convention for the image format handling and bootm related code: genimg_ - dual format shared code image_ - legacy uImage format specific code fit_ - new uImage format specific code boot_ - booting process related code Related routines are renamed and a few pieces of code are moved around and re-grouped.
