* 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."

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
