[U-Boot] Problem wit MPC8548 TSEC ethernet and Marvell 88E1145 PHY

[Alex Dubov]

I'm trying to setup a new u-boot on an old STx AMC8548 board. I discovered the reason for instability I reported earlier, namely DDR's twoT_en option was not set. However, now I have a different problem.

Attempt to access the network always fails with "Got error 4" message. I can see ARP requests being broadcast to the network but nothing else happening.

The link speed is 100Mb.
