CONFIG_64BIT
############

*(No prompt -- not directly user assignable.)*

Type: ``bool``

Help
====

.. code-block:: none

    This option tells the build system that the target system is
    using a 64-bit address space, meaning that pointer and long types
    are 64 bits wide. This option is selected by arch/$ARCH/Kconfig,
    soc/**/Kconfig, or boards/**/Kconfig and the user should generally
    avoid modifying it.

Defaults
========

No defaults. Implicitly defaults to ``n``.
