Hi Jerry,
I gave the fdtlib of your git://cideas.us/pub/scm/u-boot/u-boot-fdt.git a try on my Icecube board. I got it built with the attached patch. libfdt was actually not made and the second hunk fixes a warning (=bug?). Then I was able to read and list a blob in memory:

The bad version error is because you are running a version 16 blob and you need a version 17 blob to allow modifications. David Gibson has an intention of upconverting a v16 to v17 as part of libfdt, but neither of us has gotten around to doing it yet.
OK, I can now update the FDT, apart from "mknode", but have still problems booting Linux-2.6.21-rc7. Should it already work?
Probably not. I've only done this on the MPC8360eMDS.
Looking at the "ToDo" table it says that ./board/icecube/icecube.c needs modifications to ft_board_setup() and ./cpu/mpc5xxx/cpu.c needs modifications to ft_cpu_setup() (you should be able to copy what I did for ./board/mpc8360emds/mpc8360emds.c and ./cpu/mpc83xx/cpu.c with some minimal mods).
If that isn't the solution, I don't know where the problem lies.

Thanks. Wolfgang.
Good luck, gvb
