After #232 there are a few outstanding issues:

  • Should any other (or all) cache maintenance operations be rewritten in assembly?
    • This is necessary if the branch instructions inserted when calling DSB or ISB could cause UB
    • Or if some other subtle condition we haven't noticed requires it
  • Should any/all of the operations be static, instead of requiring an &mut SCB?
