Subject: [SPARC64]: Import OBP device tree into kernel data structures.

The basic framework is based on the PowerPC OF code.

This code even tries to get the device addressing components
correct in the full path names.

Subject: [SPARC64]: Convert sparc64 PCI layer to in-kernel device tree.

One thing this change pointed out was that we really should
pull the "get 'local-mac-address' property" logic into a helper
function all the network drivers can call.

From 8cd24ed4f8031636fb5dacb04adee9e02556ecd5 Mon Sep 17 00:00:00 2001
From: "David S. Miller" <davem@sunset.davemloft.net>
Date: Thu, 22 Jun 2006 22:08:58 -0700
Subject: [SPARC64]: Expand of_*() interfaces some more.

Import some more stuff from powerpc.

Add of_device_is_compatible(), and of_find_compatible_node().
Export some more of the other routines to modules.

Signed-off-by: David S. Miller <davem@davemloft.net>
