Hi Damiano,

Can you try revert the following patch and retest on your board?
"
commit a058052c358c3ecf5f394ff37def6a45eb26768c
Author: Stefan Agner <ste...@agner.ch>
Date:   Wed Dec 9 11:21:25 2015 -0800

    net: phy: do not read configuration register on reset
   When doing a software reset, the reset flag should be written without
    other bits set. Writing the current state will lead to restoring the
    state of the PHY (e.g. Powerdown), which is not what is expected from
    a software reset.

This patch breaks ethernet function of i.MX6 Quad Sabresd/Quad Sabreauto.
Not sure whether reverting this patch can help in your case or not. Please
try.

Thanks,
Peng.

Good morning all

I updated to latest u-boot yesterday (git pull) and ethernet was not working

reverted to tag v2016.01 with the command

$ git checkout tags/v2016.01

rebuilt, uploaded and ethernet works

As far as I can tell the only difference on the two tests (just a simple ping 
192.168.1.1) is the u-boot version
Ethernet cable was not moved and I manage to load u-boot using FEL

I can do further tests is any of you is interested.

Thanks, Damiano
