/**
* \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.
