No, it isn't. If you want to emulate the KeyStone II SoC, then please do
just that. You will find recent examples on the list of new SoCs that
have been added, including sunxi/A10 and DIGIC. So, the Ethernet
controller would be a new device in hw/net/, it is initialized by a SoC
device in hw/arm/ and to use it you need a standard machine definition,
such as the EVMK2Hx in your case (some evaluation/reference board rather
than custom industry boards). Then test that code using a Linux (or
firmware or other OS) that runs on the real board.
