+description: |
+  Test chips for ARM Versatile Express platform implement SCC (Serial
+  Configuration Controller) interface, used to set initial conditions
+  for the test chip.
+
+  In some cases its registers are also mapped in normal address space
+  and can be used to obtain runtime information about the chip internals
+  (like silicon temperature sensors) and as interface to other subsystems
+  like platform configuration control and power management.
