内存16GB生成simpoint的时候bootload挂住

在利用NEMU生成specCPU2017 simpoint时需要16GB的内存，因此修改noop.dtsi把内存增加到16GB

/dts-v1/;

/ {
    L18: soc {
        L2: clint@2000000 {
            compatible = "riscv,clint0";
            interrupts-extended = <&L4 3 &L4 7>;
            reg = <0x0 0x38000000 0x0 0x10000>;
            reg-names = "control";
            clock-frequency-mhz = <500>;
        };
        L14: serial@60000000 {
            compatible = "xilinx,uartlite";
            //interrupt-parent = <&L1>;
            interrupts = <3>;
            reg = <0x0 0x40600000 0x0 0x1000>;
            reg-names = "control";
        };
    sdhci: mmc {
      compatible = "nemu-sdhost";
            reg = <0x0 0x40002000 0x0 0x1000>;
    };
    };
  chosen {
    bootargs = "root=/dev/mmcblk0 rootfstype=ext4 ro rootwait earlycon";
  };
    L11: memory@100000000 {
        device_type = "memory";
        reg = <0x0 0x80000000 0x4 0x00000000>;
    };
};

利用NEMU 如下指令跑的时候

/xiangshang/NEMU-master/NEMU/build/riscv64-nemu-interpreter /xiangshang/linux/riscv-pk/spec2017bin/build_xz_cpu/bbl.bin -D /xiangshang/NEMU-master/spec2017CheckPoint/CPU2017Simpoint -w xz_cpu -C cpu2016-simpoint-profiling -b --simpoint-profile --cpt-interval 20000000 -r /xiangshang/NEMU-master/NEMU/resource/gcpt_restore/build/gcpt.bin

bootload挂在了Initmem setup node 0，log如下：
