0008  * If the Mbed TLS implementation of a cryptographic mechanism A depends on a
0009  * cryptographic mechanism B then if the cryptographic mechanism A is enabled
0010  * and not accelerated enable B. Note that if A is enabled and accelerated, it
0011  * is not necessary to enable B for A support.
