Hello,
Ethernet support does not work anymore when using the current U-Boot (version v2014.10) on the ODROID-X board. Bisecting shows that this happened starting from commit 874dde80169e0a0c00020e2e0bbcd380c61097e3 ("dm: usb: exynos: Use driver model for USB"): http://git.denx.de/?p=u-boot.git;a=commitdiff;h=874dde80169e0a0c00020e2e0bbc...
Below are the logs from the serial console.

As a test, reverting f56da290b8df14a058b43735494dbbb0f8521a89 ("Drop the code that doesn't use driver model for USB.") and disabling CONFIG_DM_USB in odroid_defconfig makes it work again.
