Notes:

-  Position Independent Executable (PIE) support is enabled in this
   config allowing BL31 to be loaded at any valid address for execution.

-  Since a FIP is not loaded when using BL31 as reset entrypoint, the
   ``--data="<path-to><bl31|bl32|bl33-binary>"@<base-address-of-binary>``
   parameter is needed to load the individual bootloader images in memory.
   BL32 image is only needed if BL31 has been built to expect a Secure-EL1
   Payload. For the same reason, the FDT needs to be compiled from the DT source
   and loaded via the ``--data cluster0.cpu0="<path-to>/<fdt>"@0x82000000``
   parameter.

-  The ``FVP_Base_RevC-2xAEMv8A`` has shifted affinities and requires a
   specific DTS for all the CPUs to be loaded.

-  The ``-C cluster<X>.cpu<Y>.RVBAR=@<base-address-of-bl31>`` parameter, where
   X and Y are the cluster and CPU numbers respectively, is used to set the
   reset vector for each core.

-  Changing the default value of ``ARM_TSP_RAM_LOCATION`` will also require
   changing the value of
   ``--data="<path-to><bl32-binary>"@<base-address-of-bl32>`` to the new value of
   ``BL32_BASE``.
