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. Signed-off-by: Adam Duskett <Aduskett@gmail.com> Signed-off-by: Mikael Bourhis-Cloarec <mikael.bourhis@smile.fr> [Romain: rebase on master (01.2022) - update genimage-efi.cfg to use GPT partition table and genimage-15 syntax - bump the kernel to 5.15.13 - Add host-libelf kernel dependency - Use BR2_TARGET_GRUB2_BUILTIN_MODULES_EFI after commit82d1e8c628(boot/grub2: use none platform when building for host) - Add regexp grub mandatory module for mender-grubenv - remove startup.nsh from genimage-efi.cfg after commit3efb5e31fc(board, boot, package: remove usage of startup.nsh in EFI partition)] Signed-off-by: Romain Naour <romain.naour@smile.fr> [Arnout: - abbreviate sizes and partition uuids, remove implicit ones in genimage.cfg - change data partition uuid to Linux (instead of x86_64 rootfs) - fix whitespace and shellcheck errors in scripts - remove --generate-mender-image option, always create it - remove empty directory and -O ^64bit when creating data fs - remove redundant e2fsck - add -serial stdio option to qemu call - update kernel to current stable 5.18.14 Signed-off-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be>
