platform hook needs to be implemented. The value is passed as the last
component of the option ``-fstack-protector-$ENABLE_STACK_PROTECTOR``.
- ``ENABLE_ERRATA_ALL``: This option is used only for testing purposes, Boolean
option to enable the workarounds for all errata that TF-A implements. Normally
they should be explicitly enabled depending on each platform's needs. Not
recommended for release builds. This option is default set to 0.
- ``ENCRYPT_BL31``: Binary flag to enable encryption of BL31 firmware. This
flag depends on ``DECRYPTION_SUPPORT`` build flag.
