AM5728如何修改模型树

请问AM5728能否提供模型树修改方法

我的模型树修改之后按照创龙提供的方法放到SD卡的BOOT目录下但LINUX并没有跟着更改过来

reserved-memory {
#address-cells = <2>;
#size-cells = <2>;
ranges;

ipu2_cma_pool: ipu2_cma@95800000 {
compatible = "shared-dma-pool";
reg = <0x0 0x95800000 0x0 0x3800000>;
reusable;
status = "okay";
};

dsp1_cma_pool: dsp1_cma@99000000 {
compatible = "shared-dma-pool";
reg = <0x0 0x99000000 0x0 0x4000000>;
reusable;
status = "okay";
};

ipu1_cma_pool: ipu1_cma@9d000000 {
compatible = "shared-dma-pool";
reg = <0x0 0x9d000000 0x0 0x2000000>;
reusable;
status = "okay";
};

dsp2_cma_pool: dsp2_cma@9f000000 {
compatible = "shared-dma-pool";
reg = <0x0 0x9f000000 0x0 0x800000>;
reusable;
status = "okay";
};
};
这是之前的DTS文件

这是修改后的

编译成am57xx-evm-reva3.dtb 放到SD卡中重新启动后
执行dmesg|grep -i cma 后显示CMA地址还是更改前的
