Problem with fpga2hps Bridge

Hello,
could I ask You about any progress in problem of enabling/disabling bridges? I have been searching for the answer and trying myself various manners practically for quite a long time but I am still not able to controll state of bridges. It seems not to be any official information about the change of behaviour of bridges.
I am using Linux kernel 4.1.22-ltsi (even if the version 4.1.33-ltsi should be supported by Intel/Altera now).
I thanks for any answer in advance.
Best wishes, Jan Konecny.
