3 * \brief Adjust TLS configuration
4 *
5 * Automatically enable certain dependencies. Generally, MBEDLTS_xxx
6 * configurations need to be explicitly enabled by the user: enabling
7 * MBEDTLS_xxx_A but not MBEDTLS_xxx_B when A requires B results in a
8 * compilation error. However, we do automatically enable certain options
9 * in some circumstances. One case is if MBEDTLS_xxx_B is an internal option
10 * used to identify parts of a module that are used by other module, and we
11 * don't want to make the symbol MBEDTLS_xxx_B part of the public API.
12 * Another case is if A didn't depend on B in earlier versions, and we
13 * want to use B in A but we need to preserve backward compatibility with
14 * configurations that explicitly activate MBEDTLS_xxx_A but not
15 * MBEDTLS_xxx_B.
