The only reason to use this is for syncing access to hardware between the ARM and the embedded OpenRISC core. Like Andre wrote, it only makes sense if you want to etablish some form of shared access between Linux and the Crust firmware. Using this in Linux only instead of the common spinlocks won't be fun, that hwspinlock unit is slower. greetings, Will
