    serial/ns16550: wait for TEMT before initializing · cb55b332
    Scott Wood authored
    TEMT is set when the transmitter is totally empty and all output has
    This prevents output problems (including a loss of synchronization
    observed on p2020 that persisted for quite a while) if SPL has output
    still on its way out.
