The processing of the buffer might change some data, which
will eventually trigger a cache writeback later on, corrupting
data written by the network chip. Clean the cache range
to make sure there is no writeback pending.

Set the phy device_node pointer to the equivalent cpsw slave node.
We need this, because phy drivers using this pointer for their configuration.
Create and register the phy device in cpsw_probe(), so that this phy device
can be found later by phy_device_connect() in cpsw_open().

If the GEM is used, however only FE featuren enabled, then it can not
support FBLDO configured as 16, and no RGMII/GMII configuratin bit.
So, in order to support GEM only with FE feature enabled, we do:
- using default value for FBLDO.
- using same bit for RMII/MII configuration as GEM for RGMII/GMII.

This property is wrongly documented as 'optional', although all the
ethernet units need a clock to be enabled in order to access the MDIO
interface. For that reason, this commit makes the property a required
one and fails to probe the device, when a clock is not properly provided.

Compiling the tree with allyesconfig is helpful because different
compilers (gcc, clang) or static checkers (e.g. clang's scan-build)
can then process and check more code.
This patch introduces two new configuration symbols that Kconfig files
can depend on. That way, code that is only working where a cache or DMA
implementation exists can be opted out.

Currently we have two conflicting definitions of struct usb_config_descriptor
and struct usb_interface_descriptor in the tree. This is because the USB code
uses additional fields in the structs for internal housekeeping. Add
struct usb_interface and struct struct usb_configuration with the housekeeping
data and embed the corresponding hardware structs into them. This frees the
way to use the definitions from ch9.h in the next step.

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.
