Buildroot currently has all of the needed packages to use Mender as the primary update system. However, there isn't any documentation or examples now that provide a starting point for users. This lack of documentation makes setting up a Mender based update system difficult and time-consuming. Provided in this patch series is a mender_x86_64_efi_defconfig of which sets up an x86_64 EFI based build that is ready to flash to a USB pen drive or use in a QEMU environment. The system partition schema comprises of two equally sized root partitions and a data partition that mounts to /var/lib/mender as a persistent data store partition. There is a board/mender/readme.txt provided, which gives users documentation on how to flash the built image or boot the image using QEMU as well. The post-build and post-image-efi scripts also have four options: -a --artifact-name: - The name of the artifact, this is added to /etc/mender/artifact_info -o --data-part-size: - The data partition size. -d --device-type - The device-type used by mender to catagorize registered devices.
