+ * \def MBEDTLS_ECP_INTERNAL_ALT
+ *
+ * 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.
