（仍在 DISTRO_VERSION =“3.1.11-snapshot-20221108”）
我试图创建一个自定义机器。

对于第一个“简单”测试，我获取了 stm32mp157f-dk2 板的 dts 文件（而不是来自 CubeMX）。
机器配置如下所示：

- #@NAME: stm32mp15-custom

当我现在尝试构建“分发”图像时，大多数似乎都有效，但不会生成 tf-a 的 stm32mp1-custom-trusted.dtb 文件。
- bitbake core-image-minimal

当我之前使用 MACHINE=stm32mp1 时，总是会生成相应的 u-boot-stm32mp157*-trusted.dtb 文件并且构建成功。
我假设我缺少步骤。
我知道有构建 tf-a-bl2 和 bl32 的手动步骤，但我缺少的是在 yocto 构建环境中自定义机器所需的必要步骤的文档。
谢谢！
