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.
