*Enable Software Vector Relay*

Type: ``bool``

Help
====

.. code-block:: none

    When building a bootloader firmware this option adds a
    vector table relay handler and a vector relay table, to
    relay interrupts based on a vector table pointer.
    This is only required but not limited to Cortex-M Baseline CPUs
    with no hardware vector table relocation mechanisms (e.g. VTOR).
