*Floating point Hard ABI*

Type: ``bool``

Help
====

.. code-block:: none

    This option selects the Floating point ABI in which hardware floating
    point instructions are generated and uses FPU-specific calling
    conventions.
    Note: the option is disabled for Zephyr builds with TF-M, as TF-M
    does not currently support building with Hard ABI, hence linking
    Zephyr with TF-M libraries would not be possible.
