#     powerpc/sysdev/npu: Print warning on a hash system about unsupported NPU2
#     
#     We only support radix now but when a system is booted with
#     the disable_radix parameter, there is no clear indication why NPU2 support
#     suddenly oes not work.
#     
#     This adds a warning message at the boot time.
