Device tree missing?
You need to compile it with dtc, then in u-boot use something like:
bootp; tftp 0x400000 uImage.ppc; tftp 0x600000 lite5200b.dtb
set your bootargs
bootm 0x400000 - 0x600000

kernel.org tree will also work with lite5200b, if you need ethernet
download fec/bestcomm patches from Grant's tree.
