It is perfectly true that these options are used only during CPU 
validations and not in the end product. Still, it doesn't justify why 
these options are not to be used with decompressor. Or alternately, why 
would a user intend to disable a cache when it has been implemented 
correctly and is stable? Without this change, the effect of disabling 
cache is not reflected in entirety.
