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.
