Internal Build Options ====================== |TF-A| internally uses certain options that are not exposed directly through :ref:`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).
