Charles Papon aa477b2b1c DebugPlugin now prevent the CPU catching exception when debug instruction are pushed 
Fix DataCache locking when loading mem read rsp  transaction has the flag set
Briey : Now the debug module reset the whole AXI system instead of only the CPU
Now in debug, you can access unmapped memory without crashing the CPU
