By default the Arm Ethos-N NPU will boot up in secure mode. In this mode the non-secure world cannot access the registers needed to use the NPU. To still allow the non-secure world to use the NPU, a SiP service has been added that can delegate non-secure access to the registers needed to use it. Only the HW_CONFIG for the Arm Juno platform has been updated to include the device tree for the NPU and the platform currently only loads the HW_CONFIG in AArch64 builds.
