FVP_AEM-A : SVE2 AES support missing

Hi , 

Seeing crash when my baremetal program encounter "AESE" instruction ( SVE2 AES) on  FVP_AEM-A (version: 11.25.15 (Mar  7 2024)) using ARM development studio (version: 2024.0-1).

Model params used : -C cluster0.NUM_CORES=1 -C bp.secure_memory=0 -C cluster0.has_sve=1  -C cluster0.sve.has_sve2=1 -C cluster0.sve.sve2_version=1 -C cluster0.sve.has_sve2_aes=1

i checked "ID_AA64ZFR0_EL1" register after it hits main, it shows SVE2 AES not supported.

I tried to modify cluster0.sve.has_sve2_aes to 1/2 .. still the same issue. Can anyone suggest if i am missing anything ?

Thanks
Anup
