@AmyChan-Intel thank you very much for your contribution.

Do you think you could raise PRs with forward ports for this? (This file went to the crypto repo after the split so the forward ports would need to go into https://github.com/Mbed-TLS/TF-PSA-Crypto against the development and the tf-psa-crypto-1.1 branches.)
