+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.

+-  ``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).
