[U-Boot] ZYNQ direct MAC connection

[Hannes Schmelzer]

Hello,

did anybody setup successfully setup a direct MAC connection using RGMII 
with a zynq ?
For example to a switch.

The zynq_gem driver wants to probe for phy by itself.
I already made a connection with very bad hacks in various files.

In linux such things are working with "fixed-link". Also the i.mx6 FEC 
driver (not using DM) can operate in direct-connection mode.

many thanks and best regards,
Hannes
