The content explains how to integrate an external kernel device driver as a new package in the Buildroot system, named "xyz." It involves creating a directory for the package and two essential files, Config.in and xyz.mk, which define package configuration and build instructions. The Config.in file sets up package options, while xyz.mk specifies module version, site, license, and build commands. Modifications are required in the main Buildroot Config.in file to include the new package, making it visible in the menuconfig. Finally, it outlines necessary adjustments in the source code's top-level Makefile for successful integration.
