    sl82c105: rework PIO support (take 2) · e93df705
    Sergei Shtylyov authored
    Get rid of the 'pio_speed' member of 'ide_drive_t' that was only used by this
    driver by storing the PIO mode timings in the 'drive_data' instead -- this
    allows us to greatly  simplify the process of "reloading" of the chip's timing
    register and do it right in sl82c150_dma_off_quietly() and to get rid of two
    extra arguments to config_for_pio() -- which got renamed to sl82c105_tune_pio()
    and now returns a PIO mode selected, with ide_config_drive_speed() call moved
    into the tuneproc() method, now called sl82c105_tune_drive() with the code to
    set drive's 'io_32bit' and 'unmask' flags in its turn moved to its proper place
    in the init_hwif() method.
    Also, while at it, rename get_timing_sl82c105() into get_pio_timings() and get
    rid of the code in it clamping cycle counts to 32 which was both incorrect and
    never executed anyway...
