  • Enable SPI6 on-chip driver with TX/RX selectable DMA/BDMA modes (BDMA options come from the shared HAL_Drivers Kconfig)
  • Reserve the WS2812 BDMA buffer section (.ws2812_bdma) in SRAM4 across GCC/IAR/MDK5 linker scripts for a standalone package
  • Sync CubeMX configuration and regenerate MDK5 project
  • Update README with SPI6/BDMA support status

为确保代码符合 RT-Thread 的编码规范，请在你的仓库中执行以下步骤运行代码格式化工作流（如果格式化CI运行失败）。
To ensure your code complies with RT-Thread's coding style, please run the code formatting workflow by following the steps below (If the formatting of CI fails to run).

🛠 操作步骤 | Steps

  1. 前往 Actions 页面 | Go to the Actions page
    点击进入工作流 → | Click to open workflow →

  2. 点击 Run workflow | Click Run workflow

  • Use workflow from 保持默认分支（通常为 master）
    Keep the default branch (usually master) in Use workflow from
  • 在 branch 输入框填写 PR 分支 pr/dm-mc02-spi6-bdma
    Enter PR branch pr/dm-mc02-spi6-bdma in the branch field
  • 设置需排除的文件/目录（目录请以"/"结尾）
    Set files/directories to exclude (directories should end with "/")
  1. 等待工作流完成 | Wait for the workflow to complete
    格式化后的代码将作为独立提交推送至你的分支。
    The formatting changes will be pushed to your branch as a separate commit.

完成后，提交将自动更新至 pr/dm-mc02-spi6-bdma 分支，关联的 Pull Request 也会同步更新。
Once completed, commits will be pushed to the pr/dm-mc02-spi6-bdma branch automatically, and the related Pull Request will be updated.

看了一下似乎确实是如此，rt-thread好像只是把main当成线程了，不需要保活。不过其他BSP通常因为LED闪烁保留着，所以我写的时候按习惯了。稍后推个上来修复一下吧
