*Cached RPO mapping*

Type: ``int``

Help
====

.. code-block:: none

    A design trick on multi-core hardware is to map memory twice
    so that it can be seen in both (incoherent) cached mappings
    and a coherent "shared" area.  This specifies which 512M
    region (0-7, as defined by the Xtensa Region Protection
    Option) contains the "cached" mapping.

Default
