Also increase add PLAT_ARM_SP_MAX_SIZE to override the default ARM_SP_MAX_SIZE to support Trusty image and move OPTEE_SP_FW_CONFIG documentation to build-internals.rst as it's not externally set-able.

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).
|
|
|
|
- ``FFH_SUPPORT``: This boolean option provides support to enable Firmware First
|
|
handling (FFH) of External aborts and SError interrupts originating from lower
|
|
ELs which gets trapped in EL3. This option will be set to 1 (enabled) if
|
|
``HANDLE_EA_EL3_FIRST_NS`` is set. Currently only NS world routes EA to EL3 but
|
|
in future when Secure/Realm wants to use FFH then they can introduce new macros
|
|
which will enable this option implicitly.
|
|
|
|
- ``OPTEE_SP_FW_CONFIG``: DTC build flag to include OP-TEE as SP in
|
|
tb_fw_config device tree. This flag is defined only when
|
|
``ARM_SPMC_MANIFEST_DTS`` manifest file name contains pattern optee_sp.
|
|
|
|
- ``TRUSTY_SP_FW_CONFIG``: DTC build flag to include Trusty as SP in
|
|
tb_fw_config device tree. This flag is defined only when
|
|
``ARM_SPMC_MANIFEST_DTS`` manifest file name contains pattern trusty_sp.
