Port to Cortex-M55 + MVE

[hanno-becker]

Hi @Emill, I've just come across your work on optimized implementations of ECC for Arm. First of all, thanks a lot for that, it looks amazing.

Would you be interested in porting your code to Cortex-M55, leveraging the Cortex-M Vector Extensions (MVE)? If so, please drop me a mail, and I can provide you with some more information and setup instructions for the necessary tooling.
