crypto: ecc - Add NIST P384 curve parameters
Add the parameters for the NIST P384 curve and define a new curve ID for it. Make the curve available in ecc_get_curve. Summary of changes: * crypto/ecc_curve_defs.h - add nist_p384 params * include/crypto/ecdh.h - add ECC_CURVE_NIST_P384 * crypto/ecc.c - change ecc_get_curve to accept nist_p384 Signed-off-by: Saulo Alessandre <saulo.alessandre@tse.jus.br> Tested-by: Stefan Berger <stefanb@linux.ibm.com> Acked-by: Jarkko Sakkinen <jarkko@kernel.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
