You can take a look at the online documentation:

http://www.denx.de/wiki/view/DULG/RootFileSystemDesignAndBuilding

Up now, the method starts with a small-subset (SELF), and you can add
then the files you need for your target.

However, you can use the ELDK Root Filesystem Builder (RFSB). It is not
part of ELDK iso, you have to download it yourself from the git repo:

git clone git://git.denx.de/rfsb

Eldk installation process installs files in a rootfilesystem, that can
be mounted over NFS. However, during ELDK installation all RPMs are
installed and the Filesystem is very large. For example, you can even
use native compilation on your target, and surely you do not need gcc,
header files, and so on in the final product: you need only a few of the
files you can use on the development system, and you must decide how
they match with your target's resources (RAM/FLASH).
