At the moment we have a mixture of left-over version 0 and new-format
version 1 files in arch/powerpc/boot/dts. This is potentially
confusing to people new to the dts format attempting to figure it out.
So, this patch converts all the as-yet unconverted dts v0 files and
converts them to v1. They're mechanically-converted, and not hand
tweaked so in some cases they're not 100% in keeping with usual v1
style, but the convertor program does have some heuristics so the
discrepancies aren't too bad.
I have checked that this patch produces no changes to the resulting
dtb binaries.

This patch is fixes the sequoia.dts device tree file to use the values defined
in the 440Epx data sheet from AMCC.
That fixes an issue where some devices, including graphics cards, would not
initialize properly because the PCI resource space was not big enough.

This patch changes the "max-frame-size" property to 9000 for all gbit
enabled 4xx boards. All those ports generally support jumbo frames, so
let's give the user a chance to enable it.

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.

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.

There are a few variants of the STACR register that affect more than
just the "AXON" version of EMAC. Replace the current test of various
chip models with tests for generic properties in the device-tree.

More than just "AXON" version of EMAC RGMII supports MDIO, so replace

This adds RGMII support to Sequoia DTS and sets correct phy-mode
for EMACs. According to Sequoia datasheet, both ethernet ports
are connected to RGMII interface, while ZMII is used only for MDIO.

According to PowerPC 440EPx documentation,
MAL0 is comprised of four channels (two transmit and two receive).
Each channel is dedicated to one of two EMAC cores.
This patch fixes Sequoia DTS MAL0 entry and EMAC entries,
assigning correct channel numbers to EMACs.
