ENC28J60 is a stand-alone Ethernet controller with SPI Interface
and integrated 10BASE-T PHY.
This driver was ported from linux-3.15.
The most notable barebox driver version changes:
* add device tree support;
* drop netif_msg_*() debug level checking;
* use IF_ENABLED for checking CONFIG_ENC28J60_WRITEVERIFY;
* add mii_bus support.

Marvell Orion ethernet IP originally is multi-port capable, but SoCs
using the IP usually have multiple single-port controllers built in.
Currently, orion-gbe driver registers each port device with a constant
name, which causes a name conflict with multiple controller instances.
This patch uniquifies port device name generation by prepending
controller's base register address to resolve the name conflict.

The fec has a mdio bus. This adds support for a subnode

phys start with features initialized from the phy driver
and are eventually limited by of_set_phy_supported. This
does not work with the genphy driver which starts with
no features and overwrites phydev->supported with the
values read from hardware in config_init. This overwrites
the features adjusted by of_set_phy_supported.
To fix this let the genphy driver start with full features
which are then only limited in config_init, but never
extended.

the phydev->supported field does not necessarily match the hardware
capabilities, it could be limited by the board to force the phy
to a lower speed. In this case make sure the gigabit advertise bits
are cleared on a gigabit phy.

barebox can transparently handle phys specified in the devicetree.
Use this functionality in the orion-gbe driver. This requires:
- add a device to the orion-gbe ports. This has the port device_node
attached and is set as the parent of the ethernet device so that
the ethernet code finds the correct device_node
- In the mdio-mvebu driver attach the device_node of the mdio device
to the miibus device so that the phy code finds the correct node
- call phy_device_connect instead of of_phy_device_connect.

When the ethernet device has a device_node then try finding
the associated phy via the phy-handle property.
This makes the phy handling via devicetree transparent to the
ethernet drivers.

The phy_map should be valid once a phy_device is registered. This
allows registering phys outside of mdiobus_scan.

phy_device_connect combines searching for a phy with actually attaching
it to the ethernet device. Factor out a phy_device_attach function to
have a function for each purpose. This makes the logic of phy_device_connect
simpler.

Instead of keeping track of the mac_control register value and
only writing to it when it changed just always write it. This is
more safe anyway since the mac_control register content is altered
in the soft_reset functions.

RX DMA Head Descriptor Pointer can get 0 when there is a lot of traffic,
which results in a timeout error. A good way to provoke this error is by
sending lots of ARP requests. This patch makes sure that the RX DMA Head
Descriptor Pointer is set.

The AX88772B uses only 11 bits of the header for the actual size. The other bits
are used for something else. This causes dmesg full of messages:
asix_rx_fixup() Bad Header Length
This patch trims the check to only 11 bits. I believe on older chips, the
remaining 5 top bits are unused.
