Thanks for input. I have posted another patch with mount option:

    As long this setting is not stored in the filesystem itself, it is useless.
    IIRC it just controls the endianness setting for mkfs.jffs2's
    t32() and t16() macros.
    
    That's why I think of a mount option like "force_endian=".
    
    Thanks,
