[PATCH 0/4] Enable Ethernet on StiH407 family boards

[Maxime Coquelin]

This series enables Ethernet support on STiH407 family reference design
boards.

These boards use the RTL8367 Switch as PHY.
As it is previously configured by the bootloader, we declare it as a fixed
link.

[PATCH 3/4] ARM: dts: Enable Ethernet on STi's B2120 boards

[Maxime Coquelin]

These boards are mounted with Realtek RTL8367 switch.
We consider the bootloader will have intiliazed the switch before jumping into
the kernel, so we declare it as a fixed link.
