Great, that seems to be it...
Except that nothing happens when I jump to 0x40000, no message from the 

0x40000? I recalled the entry point should be 0x400000 for simepleImage.*.elf.
So you have to change this on the file, arch/powerpc/boot/wrapper.

And also you should confirm if the upstream kernel support your board.

Additionally let's assume your bootloader create the map between the virtual
address and the physical address as 1:1. If so you want to execute from 0x40000.
 But the actual PC address should be the loader address + offset. You can get
this by readelf. Here if your loader address is zero, the offset will be pc
address, not 0x40000. You can dump your memory to check this.

kernel, nothing.
I'm a bit stumped here as my old kernel worked fine.
