 * Note that division for the native integer type is always required.

 * MBEDTLS_ECP__FUNCTION_NAME__ALT: Uncomment a macro to let Mbed TLS use your
 * alternative core implementation of elliptic curve arithmetic. Keep in mind
 * that function prototypes should remain the same.
 *
 * This partially replaces one function. The header file from Mbed TLS is still
 * used, in contrast to the MBEDTLS_ECP_ALT flag. The original implementation
 * is still present and it is used for group structures not supported by the
 * alternative.
 *
 * The original implementation can in addition be removed by setting the
 * MBEDTLS_ECP_NO_FALLBACK option, in which case any function for which the
 * corresponding MBEDTLS_ECP__FUNCTION_NAME__ALT macro is defined will not be
 * able to fallback to curves not supported by the alternative implementation.
 *
 * Any of these options become available by defining MBEDTLS_ECP_INTERNAL_ALT
 * and implementing the following functions:
 *      unsigned char mbedtls_internal_ecp_grp_capable(
 *          const mbedtls_ecp_group *grp )
 *      int  mbedtls_internal_ecp_init( const mbedtls_ecp_group *grp )

 * replacement functions implement arithmetic for the given group and 0
 * otherwise.
 * The functions mbedtls_internal_ecp_init and mbedtls_internal_ecp_free are
 * called before and after each point operation and provide an opportunity to
 * implement optimized set up and tear down instructions.
 *
 * Example: In case you set MBEDTLS_ECP_INTERNAL_ALT and
 * MBEDTLS_ECP_DOUBLE_JAC_ALT, Mbed TLS will still provide the ecp_double_jac()
 * function, but will use your mbedtls_internal_ecp_double_jac() if the group
 * for the operation is supported by your implementation (i.e. your
 * mbedtls_internal_ecp_grp_capable() function returns 1 for this group). If the
 * group is not supported by your implementation, then the original Mbed TLS
 * implementation of ecp_double_jac() is used instead, unless this fallback
 * behaviour is disabled by setting MBEDTLS_ECP_NO_FALLBACK (in which case
 * ecp_double_jac() will return MBEDTLS_ERR_ECP_FEATURE_UNAVAILABLE).
 *
 * The function prototypes and the definition of mbedtls_ecp_group and
 * mbedtls_ecp_point will not change based on MBEDTLS_ECP_INTERNAL_ALT, so your
 * implementation of mbedtls_internal_ecp__function_name__ must be compatible
 * with their definitions.

 * \def MBEDTLS_ECP_RESTARTABLE
 *
 * Enable "non-blocking" ECC operations that can return early and be resumed.
 *
 * This allows various functions to pause by returning
 * #MBEDTLS_ERR_ECP_IN_PROGRESS (or, for functions in the SSL module,
 * #MBEDTLS_ERR_SSL_CRYPTO_IN_PROGRESS) and then be called later again in
 * order to further progress and eventually complete their operation. This is
 * controlled through mbedtls_ecp_set_max_ops() which limits the maximum
 * number of ECC operations a function may perform before pausing; see
 * mbedtls_ecp_set_max_ops() for more information.
 *
 * This is useful in non-threaded environments if you want to avoid blocking
 * for too long on ECC (and, hence, X.509 or SSL/TLS) operations.
 *
 * This option:
 * - Adds xxx_restartable() variants of existing operations in the
 *   following modules, with corresponding restart context types:
 *   - ECP (for Short Weierstrass curves only): scalar multiplication (mul),
 *     linear combination (muladd);
 *   - ECDSA: signature generation & verification;
 *   - PK: signature generation & verification;
 *   - X509: certificate chain verification.
 * - Adds mbedtls_ecdh_enable_restart() in the ECDH module.
 * - Changes the behaviour of TLS 1.2 clients (not servers) when using the
 *   ECDHE-ECDSA key exchange (not other key exchanges) to make all ECC
 *   computations restartable:
 *   - ECDH operations from the key exchange, only for Short Weierstrass
 *     curves, only when MBEDTLS_USE_PSA_CRYPTO is not enabled.
 *   - verification of the server's key exchange signature;
 *   - verification of the server's certificate chain;
 *   - generation of the client's signature if client authentication is used,
 *     with an ECC key/certificate.
 *
 * \note  In the cases above, the usual SSL/TLS functions, such as
 *        mbedtls_ssl_handshake(), can now return
 *        MBEDTLS_ERR_SSL_CRYPTO_IN_PROGRESS.
 *
 * \note  When this option and MBEDTLS_USE_PSA_CRYPTO are both enabled,
 *        restartable operations in PK, X.509 and TLS (see above) are not
 *        using PSA. On the other hand, ECDH computations in TLS are using
 *        PSA, and are not restartable. These are temporary limitations that
 *        should be lifted in the future.
 *
 * \note  This option only works with the default software implementation of
 *        elliptic curve functionality. It is incompatible with
 *        MBEDTLS_ECP_ALT, MBEDTLS_ECDH_XXX_ALT, MBEDTLS_ECDSA_XXX_ALT.
