[TF-A] Does FVP and current TF-A support the SVE/SVE2 programming?

Hi all,

I want to perform some encryption/decryption in TF-A. I find that Arm provides some hardware-assisted instructions for encryption and integrity verification (e.g., AESE, SHA1...). But it seems that FVP does not support them.

I recently read Armv9 and know that Arm purposes SVE/SVE2 to accelerate the matrix computation. It seems that it can be another approach to accelerate the encryption.

Since I am a novice in Armv9 (and in FVP), thus, I want to ask: (1) Do FVP and TF-A support the SVE? If yes, how to configure it? (2) Do FVP and TF-A support the SVE2? If yes, how to configure it?

Looking forward to your reply!

Sincerely, WANG Chenxu
