Boot failed on Loongson3A-2000 machine

Hi,
    I use the kernel file in :
http://nyftp.netbsd.org/pub/NetBSD-daily/HEAD/201703172030Z/evbmips-mips64el/binary/kernel/
    to boot my Loongson3A-2000 machine but failed with the error message:
             panic: CPU type (0x146308) not supported.

Any suggestions ?
