[U-Boot] Ethernet on FDI3250 board

[Jonatan Personal]

Hi Vladimir, yes the problem is resolved, it was a problem with the size of
uboot image when enabling MII commands. I was copying just 256KB to nand
flash and the image was a little larger than that, so I increased the uboot
memory section in nand flash and it started working fine. Thanks for your
concern.

Kind regards, Jonatan.
