	Hi Simon, Magnus,

This patch series enables SMP support on the R-Car V3M SoC, by adding
the second Cortex-A53 CPU core.  It also adds the performance monitor
unit, and links it to both CPU cores.

Note that the PSCI implementation on Eagle may be a preliminary version
with some familiar quirks:
  - SMP bringup works, and both CPUs can be used,
  - Offlining CPU0 crashes the system,
  - CPU1 can be offlined, but trying to bring it online again crashes
    the system, too.

I'm confident these will be fixed in future firmware versions, just like
on H3/Salvator-X.

I'd like to understand how confident before applying this series.
I have been burnt in the past by enabling SMP before the fw/hw/sw stack
was ready (on H3 IIRC) and I'd rather not relive that experience.
