Hi!
After some testing:
u-boot-2013.01.01 + linux-3.17 => ethernet does not work
(unless ethernet is used in u-boot, for example
using ping)
u-boot-marex-20140920a + linux-3.17 => working ethernet
One of our guesses is that maybe we don't pull ethernet out of reset
in the first case?
Best regards,
Pavel

v3.17 has the reset driver framework that the stmmac driver uses to
deassert the reset.
