我按照这个页面来编译U-BOOT 的: https://software-dl.ti.com/processor-sdk-linux/esd/AM64X/latest/exports/docs/linux/Foundational_Components/U-Boot/UG-General-Info.html#getting-the-u-boot-source-code
问题1： git clone 下来的 ti-linux-firmware 里面没有 ti-sysfw 文件夹，需要的文件我再 prebuilt-images 文件夹里面找到了，为什么没有了，这个页面的教程过时了吗？
问题2：编译报错，我是在红框所示的这一步时报错的
报错信息如下：

请问这个报错要怎么解决呀？
