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