A.4.4 Booting via TFTP Using NFS File System
To boot in this mode, set the following parameters after you abort the
automatic boot sequence:
EVM # setenv bootcmd 'dhcp;bootm'
EVM # setenv serverip <ip addr of tftp server>
EVM # setenv bootfile <name of kernel image>
EVM # setenv rootpath <root directory to mount>
EVM # setenv nfshost <ip addr of nfs host>
EVM # setenv bootargs console=ttyS0,115200n8 noinitrd rw
ip=dhcp root=/dev/nfs nfsroot=$(nfshost):$(rootpath),nolock

The <root directory to mount> must match the filesystem that you set up
on your workstation. For example, /home/<useracct>/workdir/filesys.
