Booting PPC Linux

I have a uImage + dtb that use to boot on a MPC8544-like system
a few months ago.
After rebasing my code, it did not work.
I notice that in arch/ppc/lib/ppclinux.c the kernel is now called
with the device tree as a parameter.
After investigation, I copied the device tree to within 8MB of the
kernel entry point (0x0). It booted.
Is the DTB relocation a missing step?
Otherwise any suggestions on what I should look at (different kernel image)?
I have already been through the Barebox code and U-boot code (U-boot
does relocate the device tree).
