    juno: Revert FWU update detect mechanism · 4da6f6cd
    Sathees Balya authored
    The patch 7b56928a
    
     unified the FWU mechanism on FVP and Juno
    platforms due to issues with MCC firmware not preserving the
    NVFLAGS. With MCCv150 firmware, this issue is resolved. Also
    writing to the NOR flash while executing from the same flash
    in Bypass mode had some stability issues. Hence, since the
    MCC firmware issue is resolved, this patch reverts to the
    NVFLAGS mechanism to detect FWU. Also, with the introduction
    of SDS (Shared Data Structure) by the SCP, the reset syndrome
    needs to queried from the appropriate SDS field.
