The Armada 370 Mirabox has a NAND flash, so enable it in the devicetree
and add the partitions as prepared in the factory images.

In order to skip the driver's custom device detection and use only
ONFI detection, the "marvell,keep-config" parameter is used.
This is needed because we have no support for setting the timings parameters yet.

Generally, power LEDs should indicate when power is applied, and go out
once power is removed.  _Not_ annoy the developer with migraine-inducing
blinking reminicent of some badly animated television series designed to
sell sugar to children.

On a more serious note, most of these OS-specific properties aren't
necessary and should be removed.  I left two that are legitimately tying
disk LEDs to disk activity.  Other than that, we keep the state the
bootloader left them in until userspace changes the state via sysfs.

Now that mbus has been added to the device tree, it's possible to
move the PCIe nodes out of internal registers, placing it directly
below the mbus. This is a more accurate representation of the
hardware.

Moving the PCIe nodes, we now need to introduce an extra cell to
encode the window target ID and attribute. Since this depends on
the PCIe port, we split the ranges translation entries, to correspond
to each MBus window.

In order to access the SoC BootROM, we need to declare a mapping
(through a ranges property). The mbus driver will use this property
to allocate a suitable address decoding window.

The Armada 370/XP SoC family has a completely configurable address
space handled by the MBus controller.

This patch introduces the device tree layout of MBus, making the
'soc' node as mbus-compatible.
Since every peripheral/controller is a child of this 'soc' node,
this makes all of them sit behind the mbus, thus describing the
hardware accurately.

A translation entry has been added for the internal-regs mapping.
This can't be done in the common armada-370-xp.dtsi because A370
and AXP have different addressing width.

Introduce a 'internal-regs' subnode, under which all devices are
moved. This is not really needed for now, but will be for the
mvebu-mbus driver. This generates a lot of code movement since it's
indenting by one more tab all the devices.  So it was a good
opportunity to fix all the bad indentation.

This conversion will allow to keep 32 bits addresses for the internal
registers whereas the memory of the system will be 64 bits.

The Globalscale Mirabox platform uses one PCIe interface for an

Add the three external LED definitions to the device tree file on
the Mirabox.

The Mirabox user guide calls out one as a power LED, and the other
two are defined for WiFi, but as the current mwifiex drivers don't
have LED support, we make them status LEDs.

These have been tested working by writing to the appropriate
/sys/class/leds trigger.

The previous configuration used the wrong "clk" pin.  Without this
change mv_sdio worked because the bootloader would set the pin up, but
with a bootloader that does not set the pin, mv_sdio fails to detect any
card.

I have tested this change using a mwifiex_sdio wireless network adapter
over the SDIO interface.

The mvneta driver for the Marvell Armada 370/XP Ethernet devices has
gained proper clock framework integration, and the corresponding
Device Tree nodes now have a correct 'clocks' pointer.

The 'clock-frequency' properties in the various .dts files for Armada
370/XP boards have therefore become useless.
