  1. TonyMac32's post in Change CMA memory allocation size was marked as the answer   
    I just did a quick test on Le Potato, increasing CMA to 512 MB was very easy following the above instructions with the /boot/dtb/amlogic/meson-gxl-s905x-libretech-cc.dtb device tree.  The property yo uwant to change is right at the top of the file as a handle under "reserved-memory"
     
    Any value that is 0x400000 aligned should be valid, so you can experiment.
