From 27fbaa9702e548e74dffd21855769f6cedad42bd Mon Sep 17 00:00:00 2001 From: David Gibson Date: Thu, 22 Mar 2007 17:02:21 +1100 Subject: [POWERPC] Add device tree utility functions to zImage This patch adds a library of useful device tree manipulation functions to the zImage library, for use by platform code. These functions are based on the hooks already in dt_ops, so they're not dependent on a particular device tree implementation. This patch also slightly streamlines the code in main.c using these new functions. This is a consolidation of my work in this area with Scott Wood's patches to a very similar end.
