*Enable global heap for mbed TLS*

*Enable global heap for mbed TLS*

*Enable global heap for mbed TLS*

Type: ``bool``

Help
====

.. code-block:: none

    This option enables the mbedtls to use the heap. This setting must
    be global so that various applications and libraries in Zephyr do not
    try to do this themselves as there can be only one heap defined
    in mbedtls. If this is enabled, then the Zephyr will, during the device
    startup, initialize the heap automatically.
