Arnd Bergmann 84dbf97808 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."
