*Custom Section Align*

Type: ``bool``

Help
====

.. code-block:: none

    MPU_REQUIRES_POWER_OF_TWO_ALIGNMENT(ARMv7-M) sometimes cause memory
    wasting in linker scripts defined memory sections. Use this symbol
    to guarantee user custom section align size to avoid more memory used
    for respect alignment. But that needs carefully configure MPU region
    and sub-regions(ARMv7-M) to cover this feature.

Direct dependencies
===================

\ :kconfig:`ARM_MPU <CONFIG_ARM_MPU>` && \ :kconfig:`CPU_HAS_MPU <CONFIG_CPU_HAS_MPU>` && \ :kconfig:`ARM <CONFIG_ARM>`

*(Includes any dependencies from ifs and menus.)*

Defaults
========

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