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