static initialize comb table

Browse Source

MBEDTLS_ECP_FIXED_POINT_OPTIM aims to speed up ecc multiplication performance.

We compute the comb table in runtime now. It is a costly operation.

This patch add a pre-computed table to initialize well-known curves. It speed up ECDSA signature verify process in runtime by using more ROM size.
