I'm using the imx8qxp board.I have a few questions about yocto.
1. How does yocto configure and compile Linux and uboot?Because I didn't see the source code for Linux and uboot.
2. I compiled an sd card image based on i.mx_yocto_project_user 's_Guide, and the uboot phase can run on my board.Now I want to open CONFIG_AHAB_BOOT. How do I do this?
