Your kernel receives the "ip=[...]"[1] kernel parameter. If you start your
Mini2440 from NAND (without NFS root and so on) you should remove this kernel
parameter. In this case network initialization should be done from userland
instead.

[1] "ip=172.16.0.19:172.16.0.10:172.16.0.1:255.255.255.0:::"
(remove it or use "ip=none" instead, also refer
to "linux-3.0/Documentation/filesystems/nfs/nfsroot.txt")
