Devices with large amounts of flash but operating in connectivity- constrained areas can benefit from using uncompressed images as this allows delta updates using binary diff algorithms. Connectivity-constrained areas in this context are defined as areas where the connection is very slow, unstable, etcetera, where it is difficult to transfer data in large scale. Add a "none" option to the compression menu and map it to the mksquashfs -no-compression flag to enable this feature. Disable the ability to select extreme compression in this case as that makes absolutely no sense combined with no compression.
