Thanks for the advice.
So I put my u-boot.bin file on tftp and do following:
tftp 0x10400000 u-boot.bin 
protect off 0x0 0x1ffff 
erase 0x0 0x1ffff 
cp.b 0x10000000 0x0 0x1975c 
protect on 0x0 0x1ffff 
reset 

While 0x1975c is the size I get after loading the u-boot.bin file
via tftp?

Uboot> setenv ipaddr 10.0.0.11
Uboot> tftp 0x010400000 u-boot.bin
macb0: Starting autonegotiation...
macb0: Autonegotiation timed out (status=0x7849)
macb0: link down (status: 0x7849)
macb1: Starting autonegotiation...
macb1: Autonegotiation complete
macb1: link up, 100Mbps full-duplex (lpa: 0x45e1)
Using macb1 device
TFTP from server 10.0.0.1; our IP address is 10.0.0.11
Filename 'u-boot.bin'.
Load address: 0x10400000

done
Bytes transferred = 138784 (21e20 hex)

So 0x21e20 ?

Okay, I made a copy of the information.
 
Thanks a lot for your time,
