從flash上啟動根檔案系統，再用命令掛接NFS
ifconfig eth0 192.168.0.130
mount -t nfs -o nolock,vers=2 192.168.0.110:/source/rootfs



tftp -gr madplay 192.168.1.110

movi - movi     - sd/mmc r/w sub system for SMDK board
Usage:
movi init - Initialize moviNAND and show
 
 card info
movi read  {u-boot | kernel} {addr} - Read data from sd/mmc
movi write {fwbl1 | u-boot | kernel} {addr} - Write data to sd/mmc
movi read  rootfs {addr} [bytes(hex)] - Read rootfs data from sd/mmc by size
movi write rootfs {addr} [bytes(hex)] - Write rootfs data to sd/mmc by size
movi read  {sector#} {bytes(hex)} {addr} - instead of
 
 this, you can use "mmc read"
movi write {sector#} {bytes(hex)} {addr} - instead of this, you can use "mmc write"
