This patch add inital (minimal) platform support for AMD Seattle,
which mainly just define the matching ID, and specify system_off,
and sytem_reset mechanism.

Initially, the firmware only support a subset of PSCI-0.2 functions,
system-off and sytem-reset. The boot protocol is still using spin-table.

In that case, aren't you missing

cpu_up = cpu_up_send_sgi


Or are you just going to assume that the firmware is going to be updated
to support full PSCI 0.2?

I thought the platform_cpu_up() is only called from the arch/arm/arm32/smpboot.c. Is it also used for ARM64?

And yes, the firmware will support full PSCI-0.2 eventually.
