9*22439cf4SMichal Simekdescription:
10*22439cf4SMichal Simek  The Altera Freeze Bridge Controller manages one or more freeze bridges.
11*22439cf4SMichal Simek  The controller can freeze/disable the bridges which prevents signal
12*22439cf4SMichal Simek  changes from passing through the bridge. The controller can also
13*22439cf4SMichal Simek  unfreeze/enable the bridges which allows traffic to pass through the bridge
14*22439cf4SMichal Simek  normally.
