+/**
+ * \file mbedtls/config_adjust_psa_from_legacy.h
+ * \brief Adjust PSA configuration: construct PSA configuration from legacy
+ *
+ * When MBEDTLS_PSA_CRYPTO_CONFIG is disabled, we automatically enable
+ * cryptographic mechanisms through the PSA interface when the corresponding
+ * legacy mechanism is enabled. In many cases, this just enables the PSA
+ * wrapper code around the legacy implementation, but we also do this for
+ * some mechanisms where PSA has its own independent implementation so
+ * that high-level modules that can use either cryptographic API have the
+ * same feature set in both cases.

+ *
+ * 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.
