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.
