You always use a "root filesystem". With your  option,  you  mount  a
filesystem exported by your NFS server as root filesystem.

I guess you want to mount a ramdisk as rootfilesystem. To do so, make
sure your "bootargs" variable contains the string "root=/dev/ram"

Why would you want to make it part  of  the  kernel?  This  makes  no
sense.  If  you  mean how to combine the ramdisk image and the kernel
image into one image file,  then  please  see  the  multi-file  image
format of the "mkimage" tol that comes with PPCBoot.

Just do not use "root=/dev/nfs" in your "bootargs" settings.


Maybe you can get some more detailed help from reading the docs, like
