Booting PPC Linux

[Renaud Barbier]

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).


Cheers.
