    [MIPS] Sibyte: Increase minimum oneshot timer interval to two ticks. · 62247753
    Ralf Baechle authored
    For the old minimum of a single tick a value of zero would be programmed
    into the init value register which in the BCM1250/BCM1125/BCM1125H User
    Manual in the Timer Special Cases section is documented to have
    UNPREDICTABLE effect.
    
    Observable sympthoms of this bug were hangs of several seconds on the
    console during bootup and later if both dyntick and highres timer options
    were activated.
    
    In theory contiguous mode of the timers is also affected but in an act of
    hopeless lack of realism I'll assume nobody will ever configure a KERNEL
    for HZ > 500kHz but if so I leave that to evolution to sort out.
