    Coherent I-cache is causing a prefetch violation where when the core
    executes an instruction that has recently been modified, the core might
    fetch a stale instruction which violates the ordering of instruction
    fetches.
    
    The workaround includes an instruction sequence to implementation
    defined registers to trap all EL0 IC IVAU instructions to EL3 and a trap
    handler to execute a TLB inner-shareable invalidation to an arbitrary
    address followed by a DSB.
