ELDK is, as the name suggests, a Development Toolkit, i. e. a toolchain. As such, it is independent from the hardware and doesn not support any specific board, or, if you like, it supports all boards, even those that don't exist yet. What you are asking for is board support in a specific kernel tree. There is no specific support for the PQ2FADS_ZU board in our linuxppc_2_4_devel tree (which is included with the ELDK distribution). On the other hand this is a standard board which which is probably working fine, but we never tested or varified it. I guess that it is not configured for use with U-Boot.
