Somehow I thought the platform was 64-bit and found a SOC name very similar

platform.
R-Car Gen3 is ARM64 (H2 SoC -> r8a7790) and does support PSCI.
But R-Car Gen2 is ARM32 (H2 SoC -> r8a7790)
However, the code looks fairly different than what we have in Xen. For
instance secondary CPU seems to require to initialize CNTVOFF, the function
to power on a CPU also looks different.
Sorry, which code you are taking about, U-Boot or Linux?
The SMP code in Linux vs the SMP code in Xen for the R-Car. In most of
the cases, Xen should replicate what Linux does.
I am trying to understand why such differences at the moment.
