* Note that division for the native integer type is always required.
* Furthermore, a 64-bit type is always required even on a 32-bit

* 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

*
* 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.
