RISC-V SoC drivers for v6.4 Microchip: Mailbox controller & client changes for the system controller on PolarFire SoC. The controller bits have been acked by Jassi. Primarily the changes work around a "hardware" bug (really the system controller's software, but it may as well be hardware as customers cannot change it) where interrupts are not generated if a service fails. The mailbox controller driver is tweaked to use polling, rather than interrupt, mode and there are some changes to timeout code required in the client driver as a result. There's some opportunistic cleanup that I performed while doing the swap too. Canaan: A single fix for some randconfig issues that crop up when !mmu is enabled for 32-bit kernels, due to my changes in a previous release that swapped out select based entablement of the driver.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
