 *
 * The bignum code uses double-width division to speed up some operations.
 * Double-width division is often implemented in software that needs to

 * type is usually detected automatically through preprocessor macros,

 * By default division is assumed to be usable if the type is present.
 * Uncomment this option to prevent the use of double-width division.
 *
 * Note that division for the native integer type is always required.
 * Furthermore, a 64-bit type is always required even on a 32-bit
 * platform, but it need not support multiplication or division. In some
 * cases it is also desirable to disable some double-width operations. For

 * MBEDTLS_ECP__FUNCTION_NAME__ALT: Uncomment a macro to let mbed TLS use your

 *
 * 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.
 *
 * Any of these options become available by defining MBEDTLS_ECP_INTERNAL_ALT
 * and implementing the following functions:

 * otherwise.
 * The functions mbedtls_internal_ecp_init and mbedtls_internal_ecp_deinit are

 *
 * Example: In case you uncomment 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 is
 * supported (your mbedtls_internal_ecp_grp_capable function returns 1 when
 * receives it as an argument). If the group is not supported then the original
 * implementation is used. The other functions and the definition of
 * mbedtls_ecp_group and mbedtls_ecp_point will not change, so your
