Yep, I'm working on a software implementation of ECDSA. Currently have the OpenSSL implementation for the nistp256 curve isolated, debugging a test program that verifies a signature on data that was randomly generated, then will need to clean up unnecessary code and fit it into U-Boot.
CC'd my @linux.microsoft.com email, I prefer to use that one from now on.
All the best, Tim

This test verifies that ECDSA_UCLASS is implemented, and that ecdsa_verify() works as expected. The definition of "expected" is "does not find a device, and returns -ENODEV".
The lack of a hardware-independent ECDSA implementation prevents us from having one in the sandbox, for now.
Yes we do need a software impl at some point. Any update on that?
