24178825SdfrDescription:
25178825Sdfr		Contains the platform specific cycle value to wait after a
26178825Sdfr		reset command is issued. If the value is chosen too short,
27178825Sdfr		then the HW will issue a reset failure interrupt. The value
28178825Sdfr		is platform specific and should not be changed without
29178825Sdfr		consultance.
