[U-Boot] Ethernet not functional on i.MX6DL Sabre Auto

[Miquel RAYNAL]

Hi,

I am using a Sabre Auto board with an i.MX6 Dual Lite.

When I compile U-boot with defconfig file mx6dlsabreauto_defconfig, the
network is not functionnal. Only the orange LED on the RJ45 port is
blinking and dhcp requests never end. In menuconfig I saw numerous
unselected options that I guess should be enabled. But event with that,
I could not get through:

CONFIG_NET_RANDOM_ETHADDR=y
CONFIG_PHYLIB=y
CONFIG_NETDEVICES=y
CONFIG_FEC_MXC=y

The issue is present in v2017.05 and v2017.07 (did not tried previous
versions). Any idea of what could possibly be wrong ?

Boot log follows.

Thank you,
Miquèl
