If you want to got this path then you have to provide a get_time_ns() symbol for all Arm architetures and decide during runtime if you can use the architected timer. Alternatively playing tricks like this might work: select HAS_PBL_CLOCKSOURCE if !CPU_32v4T && !CPU_32v5 && !CPU_32v6 (Although this of course gives you timer functionality only when all non v7 architectures are disabled.
