Hello.
You shuld compile the kernel with options 
CONFIG_NFS_FS=y

CONFIG_NFS_V3=y

CONFIG_ROOT_NFS=y

You will need set some parameters for the kernel, for examlpe

# setenv bootargs console=ttyS0,115200n8 noinitrd ip=${OSK_IP}:${PC_IP}:${GATEWAY_IP}:${NETMASK}:osk:eth0:off root=

/dev/nfs rw nfsroot=${PC_IP}:/data/rootfs2.6,nolock mem=32M

# saveenv

Check if server nfs work on ip 140.113.179.57, and if you can mount folder on this pc where is running server nfs.
