3 * \brief Adjust legacy configuration configuration
4 *
Antonio de Angelisa0b00f42024-09-18 12:07:25 +01005 * This is an internal header. Do not include it directly.
6 *
7 * Automatically enable certain dependencies. Generally, MBEDTLS_xxx
Antonio de Angelis8bb98512024-01-16 14:13:36 +00008 * 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.
