Hi!
v2 of the SoCrates comes with a different PHY, IIRC. So we might
want to add some checking on the PHY model here at some time.
I don't have a socratesV2 and U-Boot does not support it either. Please either
mail me a socratesV2 or send a subsequent patch to add support for socratesV2,
I am open to either method.
I'll send a follow-up patch for this.
Thanks,
Stefan
