+/**
+ * \file mbedtls/config_adjust_psa_superset_legacy.h
+ * \brief Adjust PSA configuration: automatic enablement from legacy
+ *
+ * To simplify some edge cases, we automatically enable certain cryptographic
+ * mechanisms in the PSA API if they are enabled in the legacy API. The general
+ * idea is that if legacy module M uses mechanism A internally, and A has
+ * both a legacy and a PSA implementation, we enable A through PSA whenever
+ * it's enabled through legacy. This facilitates the transition to PSA
+ * implementations of A for users of M.
