LX2160ardb_rev2:

Does u-boot support ECC/ECDSA verification without using hw SEC engine?

Is there any existing implementation available in u-boot (e.g. open-ssl) for ECC/ECDSA verification without using hw SEC engine?

Doing ECC/ECDSA may be taking too long without SEC engine.
LSDK only provide RSA support.
There are ECC/ECDSA reference code on the internet. We neither support or endorse it. Customer can use it at their own risk.
