   12 description: |
   13   PolarFire SoC devices include a microcontroller acting as the system controller,
   14   which provides "services" to the main processor and to the FPGA fabric. These
   15   services include hardware rng, reprogramming of the FPGA and verfification of the
   16   eNVM contents etc. More information on these services can be found online, at
   17   https://onlinedocs.microchip.com/pr/GUID-1409CF11-8EF9-4C24-A94E-70979A688632-en-US-1/index.html

   19   Communication with the system controller is done via a mailbox, of which the client
   20   portion is documented here.
