+  Template for ArmEb DebugAgentLib. \r
+\r
+  For ARM we reserve FIQ for the Debug Agent Timer. We don't care about \r
+  laytency as we only really need the timer to run a few times a second \r
+  (how fast can some one type a ctrl-c?), but it works much better if\r
+  the interrupt we are using to break into the debugger is not being\r
+  used, and masked, by the system. \r
