    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.

commit 7442e83ca83868ec04b2fbb679d6162ddb0744b7

    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.

    Subject: [PATCH] [gta02] Disable hardware ECC unless we get instructed to enable it
         This is restoring the old behavior in regard to ECC. Even if
         hardware ECC was compiled in we didn't use it. Make this a runtime
         option. If the bootloader passes hardware_ecc we will enable the
         hardware ECC for real.

    lis302dl-allow-unloading-module.patch
    
    This patch fixes module unloading for the accelerometer (actually module
    loading failed before). The two problems were that the interrupt was not
    unregistered, and that the device was left in a "strange" state.

    always-call-resume-dependencies.patch
    
    Attached is a patch that has greatly reduced the frequency of failures
    to resume (due to an oops from the glamo resume handler), and the
    dreaded "white screen after resume".  I can't say that it fixes all of
    these, although I have yet to see the white-screen since applying this
    patch and suspending/resuming several hundred times (with the 30-second
    suspend on the 2008.8 image and the endless stream of GSM error messages
    generated by something in that image, it has proved to be very useful to
    do an automated stress test!)
    
    This patch will apply to stable, and should make stable slightly more,
    well, "stable".
    
    [Feel free to remove the debug messages if someone feels strongly about
    that; I left them in because I think they might be useful in triaging
    further crashes; I'm not at all convinced that this patch will fix all
    the cases of resume failures.]
    
    [[And, yes, this is ugly, really ugly.]]
    
    [[[Oh yeah - there's still one extreme case that will result in an oops:
     if a dependent driver is built as a module, and it is unloaded, and it
    happened that the preceding suspend/resume was aborted, and that abort
    happened between the dependent driver and the driver upon which it is
    dependent, then a list entry will be left behind referencing the
    unloaded module.  There's just no good way to fix that given the way the
    resume dependency plumbing is connected up right now, so just avoid
    using modules for any of the drivers involved in the resume dependency
    stuff.]]]

        always-call-resume-dependencies.patch
    
        Ensure that a dependent resume handler is always executed,
        even if the resume handler for driver upon which it is
        dependent never suspends (and therefore never resumes either).
        Also make sure that we do not end up with duplicate
        dependencies registered, something that can happen if the
        suspend is aborted due to driver failure or an early resume
        (such as occurs when the GSM interrupts during suspend).
