+   * When the new compilation option MBEDTLS_PSA_STATIC_KEY_SLOTS is enabled,
+     key store uses static key slot buffers instead of dynamically allocated
+     ones.
+   * The size of each static key slot buffer is determined by
+     MBEDTLS_PSA_STATIC_KEY_SLOT_BUFFER_SIZE. If not set, its default value
+     is set to accomodate for the largest PSA asymmetric/symmetric key enabled
+     in the build.
