Can you please use mainline, i. e. the master branch at git://git.denx.de/u-boot.git instead? > Please, do you have an idea of what could I be missing? Well, there is a "Possible iMX27 intermittent Ethernet connection issue rework" issued by LPD on 7/8/2008; in essence the PHY's internal 1.8V core regulator may shut off at power up. To work around this, try and implement the following two hardware modifications: 1) Populate R841 with a 4.7K resistor. (This forces the internal core regulator off for the LAN8700. R841 is located on top of the PCB just "above" the LAN8700 IC. 2) Add a jumper wire from U125.5 to C561.1. This connects the on board 1.8V rail to the core ensuring that it is always powered. And no, I don't guarantee you for anything.
