You have to replace nfsroot=/path/to/nfs/root with some valid path.
Since your dhcp server does not pass a root server ip you'll have to add
that aswell, so your nfsroot should look like
nfsroot=192.168.x.y:/path/to/nfsroot. Try 'edit /env/config' to edit
the parameter to your needs. Do not forget saveenv afterwards.

To boot from Nand also edit /env/config and adjust the kernel_loc and
rootfs_loc variables.
