ecc6cd73b7 [POWERPC] Start removing linux,network-index in favour of aliases
This patch alters the bootwrapper for a number of machines (roubhly
all 4xx based cuboot or treeboot platforms) to use aliases instead of
the linux,network-index hack to work out which MAC address to attach
to which ethernet device node.

The now obsolete linux,network-index properties are removed from the
corresponding device trees.  This won't break backwards compatiblity,
because in cases where this fixup code is relevant, the device tree is
part of the kernel image.

The references to linux,network-index are removed from
booting-without-of.txt.  Not only is it now deprecated, but as a hack
applicable only when the device tree blob and fixup code were in the
same image, this property never belonged in booting-without-of.txt
which describes the interface between the kernel and firmware or
bootloaders which produce a device tree.  By the time the device tree
reaches the kernel, all the MAC addresses must be fully filled in.

72fda1148e [POWERPC] 4xx: Rename CPU nodes to avoid dtc incompatibility
Recent DTC versions disallow certain special characters in full paths without
being quoted with {}.  That however breaks compatibility with older DTC
versions.  Work around this by renaming the CPU nodes for the 4xx files to a
generic node name, and specify the processor type in the model property of the
CPU node.

5be9419ac6 [POWERPC] 4xx: remove bogus "ranges" property in Bamboo EBC node
This removes a bogus empty "ranges" property in the EBC device node
of the Bamboo board device-tree.

The "ranges" property should be created by the wrapper code when it is
implemented.  Until then, remove the empty property since it incorrectly
implies that there is a 1:1 address mapping between the EBC and the OPB.

This also fixes a warning from newer DTCs.

007b6aa811 [POWERPC] 4xx: Wire up 440EP USB controller support to Bamboo board
This adds the definition of the on-chip OHCI controller to the
Bamboo board's device-tree. This is enough to get it probed and
working, though a separate patch fixing a bug in the OHCI driver
is needed to make it reliable.
