I know it is a real bad assumption. However, the RIO initial ID is only transported to driver by kernel parameter "riohdid", which can not distinguish the multi rio controllers. It may be more better add a "rio-id" property in RIO dts node, but the u-boot need some changes to support the rio-id assignment. Cheers! Wei.
