The services actually provided by the system controller are not documented so add some words about what the system controller can actually do. Add a link to the oneline documentation with the specific details of each individual service. Also, drop the unneeded label from the example.

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
|
|

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