*ARM architected timer is affected by ARM erratum 740657*

Type: ``bool``

Help
====

.. code-block:: none

    This option indicates that the ARM architected timer as implemented
    in the target hardware is affected by the ARM erratum 740657 (comp.
    ARM Cortex-A9 processors Software Developers Errata Notice, ARM
    document ID032315) which leads to an additional, spurious interrupt
    indication upon every actual timer interrupt. This option activates
    the workaround for the erratum within the timer driver.

Direct dependencies
