    fix-glamo-crank-memory-to-90MHz.patch
    
    This changes Glamo memory and now host bus PLL to 90MHz from
    80MHz, as recommended by S-Media.  Bandwidth should go up
    by 12.5% by this in raw terms anyway.

    fix-glamo-turbo-host-interface.patch
    
    Until now, we forced Glamo wait states to 3 on read and write
    actions -- on the GLAMO side of the fence.  This reduces them
    to "0", although nWAIT is still briefly operated I saw.  This
    should reduce all memory bus timing by 3 Glamo Host bus clocks,
    60ns at 50MHz.
    
    In addition, until now we used PLL1 (50MHz) for host bus clock.
    Now, we use PLL2 (80MHz) for host bus clock, so all transactions
    complete quicker on Glamo side, it's a raw 60% improvement.
    
    These changes do not appear to impact correct operation of Glamo
    SD Card or video after testing for a week.

    use-gta02-glamo-mci-sd-dynamic-clock.patch
    
    This patch uses the new glamo-mci slow clock ratio
    patch in order to dynamically reduce SD Card clock
    rate when the GPS unit is powered on GTA02.

    add-glamo-mci-slower-clocking-dynamic-switching.patch
    
    This patch gives glamo-mci a concept of a platform-defined
    dynamic clock slowing callback.  It means that platform code
    can associate some completely external state to decide if
    we run the SD clock at normal rate or a rate divided by a
    module parameter "sd_slow_ratio", which you can set on
    kernel commandline like this:
    
    glamo_mci.sd_slow_ratio=8
    
    you can also change it at runtime by
    
    echo 8 > /sys/module/glamo_mci/parameters/sd_slow_ratio
    
    If no platform callback is defined, then no slow mode
    is used.  If it is defined, then the default division
    action is / 8, eg, 16MHz normal -> 2MHz slow mode.

    fix-allow-full-sd-voltage-range-selection.patch
    
    Until now we just drove the SD Card at 3.3V all the time.  But in
    fact we can do better, and use a voltage negotiated with the
    SD Card itself.
    
    With the shipping 512MB Sandisk SD Card, 2.7V is negotiated which
    gives 1.7dBm reduction in power on all the SD Card lines and should
    further reduce GPS perturbation during SD Card usage.
