* \def MBEDTLS_ECP_EARLY_RETURN
*
* Enable "non-blocking" ECC operations that can return early and be resumed.
*
* This enables \c mbedtls_ecp_set_max_ops() and allows various ECC functions
* to return \c MBEDTLS_ERR_ECP_IN_PROGRESS when needed.
*
* TODO: depending on other choices, this might need to be disabled by default
* in order to avoid changing the ABI. Revisit that later.
*
* Comment this macro to disable non-blocking ECC computations.
