  ARM: shmobile: rcar-gen2: Make sure CNTVOFF is initialized on CA7/15 (2017-09-18 08:10:44 +0200)

Renesas ARM Based SoC Updates for v4.15

* Prepare to enable SMP on R-Car E2 (r8a7794).

  Geert Uytterhoeven says:
  "The main hurdle here is that R-Car Gen2 boot loaders do not initialize
   the arch_timer CNTVOFF register, which thus needs workarounds on Linux.

   - The first patch adds a definition for MON_MODE, as suggested by Marc
     Zyngier,
   - The second patch makes sure CNTVOFF is initialized for boot and
     secondary Cortex-A15 and Cortex-A7 CPU cores, like is already done for
     the boot Cortex-A7 CPU core.  Without this, the ARM arch timer does
     not work on secondary CPU cores."

   A follow-up patch to enable SMP in DT on R-Car E2 (r8a7794) is currently
   deferred unto v4.16 as it depends on the above.

* Enable low-level debugging support for RZ/G1E (r8a7745).

  Fabrizio Castro says, "RZ/G1E uses SCIF4 for the debug console."
