- * Expose a part of the internal interface of the Elliptic Curve Point module.
- *
- * 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 )
- *      void mbedtls_internal_ecp_free( const mbedtls_ecp_group *grp )
- * The mbedtls_internal_ecp_grp_capable function should return 1 if the
- * 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.
- *
- * Uncomment a macro to enable alternate implementation of the corresponding
- * function.
