[TF-M] TF-M PSA key management

Hi All,

I see that the PSA crypto API v1.0 spec says "This specification only defines policies that restrict keys to a single algorithm, which is consistent with both common practice and security good practice. ", but the TF-M code defines two algs in the policy struct. Which will be the path going forward?

struct psa_key_policy_s { psa_key_usage_t usage; psa_algorithm_t alg; psa_algorithm_t alg2; };

I also see psa_open_key() and psa_close_key() were removed from the spec. Any plans to remove from TF-M code in the future?

Regards,
