I modified your patch and after that the kernel compiles. Please find

Hi Olof,

Many thanks for your patch! :-) The RC2 of kernel 4.15 boots without any 
problems on my P.A. Semi Nemo board (A-EON AmigaOne X1000). I don’t need 
the additional boot argument 'pci=pcie_scan_all' anymore.

Is it possible to merge it via the powerpc tree?

Thanks,
Christian
