  如果DMA要访问​ → 必须用非缓存宏
  如果多核要共享​ → 必须用非缓存宏
  如果频繁被中断更新​ → 建议用非缓存宏
  其他情况​ → 不用修饰，让编译器优化
3 注意配置顺序 IO-时钟-外设
4 XDMA，作为主设备连接到 AXI 系统总线  HDMA，作为主设备连接到 AHB 外设总线 
  当 XDMA 的 destination 为 DRAM 时，如果 burst 大于等于 16，那 destsize 必须为 64bit。
  DMAMUX 的输出 0∼7 连接到外设总线 DMA 控制器 HDMA，DMAMUX 的输出 8∼15 连接到系统总线 DMA 控制器 XDMA
  它们都连接在统一的 DMAMUX（DMA 多路复用器）
  DMAMUX将所有外设的 DMA 请求（Request）统一管理，然后根据你的配置分配给 HDMA 或 XDMA 的任意空闲通道
5 注意cfg文件和一些前置的工程配置文件，可能导致编译出错 运行出错 仿真不了 重点：链接文件、yaml、板级cfg文件
