From b3bea15d29799797d1486aeddf883404a2e05c81 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Thu, 24 Jan 2008 22:41:05 -0600 Subject: [POWERPC] bootwrapper: Add find_node_by_compatible Add the ability to find a device node by just what its compatible with. This is useful in cases that we don't have a prop to find the node with.
