Merge tag 'riscv-for-linus-5.18-mw0' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux

Pull RISC-V updates from Palmer Dabbelt:

 - Support for Sv57-based virtual memory.

 - Various improvements for the MicroChip PolarFire SOC and the
   associated Icicle dev board, which should allow upstream kernels to
   boot without any additional modifications.

 - An improved memmove() implementation.

 - Support for the new Ssconfpmf and SBI PMU extensions, which allows
   for a much more useful perf implementation on RISC-V systems.

 - Support for restartable sequences.

+description: |
+  PolarFire SoC devices include a microcontroller acting as the system controller,
+  which provides "services" to the main processor and to the FPGA fabric. These
+  services include hardware rng, reprogramming of the FPGA and verfification of the
+  eNVM contents etc. More information on these services can be found online, at
+  https://onlinedocs.microchip.com/pr/GUID-1409CF11-8EF9-4C24-A94E-70979A688632-en-US-1/index.html
+
+  Communication with the system controller is done via a mailbox, of which the client
+  portion is documented here.
