functionality was not exposed to the ethernet core. This commit exposes

8bd37ce3cd drivers: net: add marvell MDIO driver
This patch adds a separate driver for the MDIO interface of the
Marvell Ethernet controllers based on driver model. There are two
reasons to have a separate driver rather than including it inside
the MAC driver itself:
  *) The MDIO interface is shared by all Ethernet ports, so a driver
     must guarantee non-concurrent accesses to this MDIO interface. The
     most logical way is to have a separate driver that handles this
     single MDIO interface, used by all Ethernet ports.
  *) The MDIO interface is the same between the existing mv643xx_eth
     driver and the new mvneta/mvpp2 driver. Even though it is for now
     only used by the mvneta/mvpp2 driver, it will in the future be
     used by the mv643xx_eth driver as well.

This driver supports SMI IEEE for 802.3 Clause 22 and XSMI for IEEE
802.3 Clause 45.

This patch also adds device tree binding for marvell MDIO driver.

01c9f047ac doc: bindings: add mdio.txt describing generic MDIO properties
Adds a binding document for mdio.  A notable deviation from corresponding
Linux binding is the introduction of device-name optional property, which
can be used to name MDIO buses.  Two reset optional properties described
by Linux binding are also not present as they don't seem to be used in
U-Boot at this time.

6b3abc0482 net: mdio-uclass: name MDIO according to device-name property if preset
Use the optional property device-name to name the MDIO bus.  This works
around limitations with using the DT node name on devices such as
Armada-8040, which integrates two cp100 cores, both featuring MDIOs at the
same relative offsets and with the same DT node names.
The concept was originally proposed by Marvell as a custom property called
mdio-name specific to Marvell driver.  This patch uses the more generic
property device-name and moves this into MDIO class code so other can use
it as well.

These are some very late changes mostly required to get 64-bit
division working on ARC boards.

For that we had to import missing parts of libgcc and add compiler
flags to EMSDP which otherwise used very simple profile for compliation.

And while at it another fix for EM SDP initialization is inluded as well.

968b98bc27 arc: emsdp: Add more platform-specific compiler options
Even though EM SDP is FPGA-based board and different FPGA
images (known as .bit-files) are awailable for the board still
there's a common subset of options we may rely on for all configs.

These are:
 * Normalizer
 * Swap instructions
 * Simple multiplier
 * Barrel-shifter
 * Floating-point unit
 * Shorter instructions (code density)

This among other improvements allows to compile code with
64-bit divisions, see [1].
