From d69a8e6387adcd79c29666930bc64fffd2a3f456 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Thu, 21 Jul 2011 01:52:57 +0200 Subject: [PATCH] device tree: add nop_node We have a qemu internal abstraction layer on FDT. While I'm not fully convinced we need it at all, it's missing the nop_node functionality that we now need on e500. So let's add it and think about the general future of that API later.
