You probably want to start by reading the documentation, for example
sections "9.5. Root File System: Design and Building"[1] and "9.6.
Root File System Selection" [2] in the DULG.

For a qick start you can use the pre-built SELF ramdisk image in the
/opt/eldk/ppc_6xx/images/ directory.

For building a customized root file system you can either follow the
instructins for manual building in the above mentioned sections of the
documentation, or try the RFSB, our root file system builder [3].


Note: I have no ide what you are trying to do, but please note that a
ramdisk (or initramfs) based root file system is almost always the
worst of all possible choices, especially in terms of memory footprint
and boot times.  I strongly recommend to check other options as well.
