Without aliases we see that the CPU device sequence numbers are set randomly and the cpu list/detail command will show it as follows: => cpu list 1: cpu@1 rv64imafdc 2: cpu@2 rv64imafdc 3: cpu@3 rv64imafdc 0: cpu@4 rv64imafdc Seems like CPU probing with dm-model also relies on aliases as observed in case spi. The fu540-c000-u-boot.dtsi has cpu nodes and so adding corresponding aliases we can ensure that cpu devices are assigned proper sequence as follows: => cpu list 1: cpu@1 rv64imafdc 2: cpu@2 rv64imafdc 3: cpu@3 rv64imafdc 4: cpu@4 rv64imafdc Signed-off-by: Sagar Shrikant Kadam Reviewed-by: Pragnesh Patel Reviewed-by: Bin Meng --- diff --git a/arch/riscv/dts/hifive-unleashed-a00-u-boot.dtsi b/arch/riscv/dts/hifive-unleashed-a00-u-boot.dtsi index 303806454b..e037150520 100644 --- a/arch/riscv/dts/hifive-unleashed-a00-u-boot.dtsi +++ b/arch/riscv/dts/hifive-unleashed-a00-u-boot.dtsi @@ -8,6 +8,10 @@ / { aliases { + cpu1 = &cpu1; + cpu2 = &cpu2; + cpu3 = &cpu3; + cpu4 = &cpu4; spi0 = &qspi0; spi2 = &qspi2; };
