.. rubric:: Enable Standby

.. attention::

For this release, in order to enable Standby, it is required for this
`patch <https://github.com/ARM-software/arm-trusted-firmware/commit/7f5ff95b39cc64ea70206fa58fd3e5aae0c33e7d>`__
to be applied to ARM Trusted Firmware.

After applying the patch, ATF will need to be re-built and then
re-packaged in the :file:`tispl.bin` file to ensure the changes take
effect. U-Boot provides the :file:`tispl.bin` file, so U-Boot will need
to be re-built after TF-A. To learn more about TF-A and how to rebuild
it, please refer to :ref:`foundational-components-atf`. For rebuilding
U-Boot and generating the new :file:`tispl.bin` follow
:ref:`Build-U-Boot-label`.

In order to enable Standby the `k3-am62x-sk-lpm-standby.dtso
<https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/arch/arm64/boot/dts/ti/k3-am62x-sk-lpm-standby.dtso?h=11.01.05>`__
overlay should be applied. Refer to :ref:`How to enable DT overlays
