[TF-M] Internal Trusted Storage

Hi team,

Can you help me with this statement that "Currently, the TF-M Secure Storage service implements PSA Protected Storage version 1.0-beta2. There is not yet an implementation of PSA Internal Trusted Storage in TF-M." Our SoC does NOT have internal flash, but we have OTP where we keep the confidential data. Can you help how to handle this ITS situation. I wonder if PSA level-2 certification requires ITS? Thanks

BR
