Dear Fabio Estevam,

mx28evk has a LAN8270 ethernet phy and we can use the phylib framework.
One of the advantages of converting to phylib is that we no longer see a timeout prior to the first transfer in the 'tftp' command.

After applying this patch I get:
U-Boot 2013.04-11810-gd6d75ec-dirty (Jul 12 2013 - 01:15:03)
CPU: Freescale i.MX28 rev1.2 at 454 MHz BOOT: SSP SD/MMC #0, 3V3 DRAM: 128 MiB MMC: MXS MMC: 0 Video: MXSFB: 'videomode' variable not set! In: serial Out: serial Err: serial Net: Phy not found
I still get this 'Phy not found' message, but I think this is not related to the board code.
This is because PHYlib doesn't know your PHY. You might need to add a definition for it into drivers/net/phy/smsc.c
mx28evk uses a LAN8270.
drivers/net/phy/smsc.c has an entry for "SMSC LAN8710/LAN8720", so not sure why it fails to recognize it. I haven't debugged it yet.
Which phy does sc_sps_1.h use? Is it also a 8720? Is the phy recognized on boot?
I think it's 8720 , but it's recognised , yes. Are you sure the PHY addresses are correct ? You can dig into phylib a bit and see what IDs does it report.
I think Fabio needs to define CONFIG_PHY_SMSC and use PHY address 3.
