Reading the commit title/description gives the impression that you are
adding support with PSCI 0.2.
While it has been added in Xen 4.5, this patch avoids to copy the PSCI
0.2 node from the host DT to DOM0 DT (because we generate it).
Please update the commit title/message according the behavior of the code.
Regards,

Please ignore this series. I have missed to update
processor_implementers[] with cavium in xen/arch/arm/setup.c
