| Since 2022, U-Boot's tool of choice for this task is [[https://u-boot.readthedocs.io/en/latest/develop/package/binman.html|binman]]. This tool uses a platform-specific config file that specifies what components should be included and where they should be placed in memory. For our platform (i.e.: i.MX8M Quad) this file would be ''arch/arm/dts/imx8mq-u-boot.dtsi''. | Since 2022, U-Boot's tool of choice for this task is [[https://u-boot.readthedocs.io/en/latest/develop/package/binman.html|binman]].
