The "mss_top_scb" register region on PolarFire SoC contains many different functions, including controls for the AXI bus and other things mainly of interest to the bootloader. The interrupt register for the system controller's mailbox is also in here, which is needed by the operating system.

title: System Controller Devices
|
|
|
|
description: |
|
|
System controller node represents a register region containing a set
|
|
of miscellaneous registers. The registers are not cohesive enough to
|
|
represent as any specific type of device. The typical use-case is
|
|
for some other node's driver, or platform-specific code, to acquire
|
|
a reference to the syscon node (e.g. by phandle, node path, or
|
|
search using a specific compatible value), interrogate the node (or
|
|
associated OS driver) to determine the location of the registers,
|
|
and access the registers directly.
