description: |+
  The ARM RealView series of reference designs were built to explore the Arm11,
  Cortex-A8, and Cortex-A9 CPUs. This included new features compared to the
  earlier CPUs such as TrustZone and multicore (MPCore).

      - description: ARM RealView Emulation Baseboard (HBI-0140) was created
          as a generic platform to test different FPGA designs, and has
          pluggable CPU modules, see ARM DUI 0303E.
