Internal Build Options
|TF-A| internally uses certain options that are not exposed directly through
:ref:`build-options <build options>` but enabled or disabled indirectly and
depends on certain options to be enabled or disabled.
.. _build_options_internal:
- ``CTX_INCLUDE_EL2_REGS``: This boolean option provides context save/restore
operations when entering/exiting an EL2 execution context. This is of primary
interest when Armv8.4-SecEL2 or RME extension is implemented.
Default is 0 (disabled). This option will be set to 1 (enabled) when ``SPD=spmd``
and ``SPMD_SPM_AT_SEL2`` is set or when ``ENABLE_RME`` is set to 1 (enabled).
