    • FEAT_NMI
    • FEAT_CSV2_3
    • FEAT_ETS2
    • FEAT_Spec_FPACC
  • The 'max' CPU and any new CPU types will default to a 1GHz generic timer frequency rather than the old 62.5MHz (this is architecturally required from ARMv8.6 onwards)
  • The emulated GICv3 also now has NMI support
  • Changes to existing board models:
    • Add DM163 display to B-L475E-IOT01A board
