    Do not enable SVE on pre-v8.2 platforms · 3872fc2d
    David Cunado authored
    
    Pre-v8.2 platforms such as the Juno platform does not have
    the Scalable Vector Extensions implemented and so the build
    option ENABLE_SVE is set to zero.
    
    This has a minor performance improvement with no functional
    impact.
