This may serve as a\nreference for users looking to integrate efibootguard into their system.\n\nefibootguard can be built for multiple architectures, but for now this\npatch series only builds for x86_64 (since that was what the project I\nadded efibootguard to used). Support for additional architectures\n(including arm, aarch64 and riscv) will come in future follow-up patches.\nI expect to do that once this series has been merged.\n\nThe example recipe has been boot-tested on QEMU with OVMF firmware and\nI have confirmed the image boots & runs as expected.\n\nFeedback welcome!\n\nSigned-off-by: Christopher Obbard <obbardc@gmail.com>\n---\nChanges in v2:\n- Rebase on top of buildroot 2026.02\n- Update efibootguard to v0.22\n- Link to v1: https://lore.kernel.org/r/20251219-wip-obbardc-boot-efibootguard-initial-pkg-v1-0-0f307ee73919@gmail.com\n\n---\nChristopher Obbard (2):\n boot/efibootguard: new boot package\n board/pc-efibootguard: add example efibootguard recipe\n\n DEVELOPERS | 5 +++\n board/pc-efibootguard/genimage.cfg | 59 +++++++++++++++++++++++++++\n board/pc-efibootguard/linux-efistub.fragment | 4 ++\n board/pc-efibootguard/post-build.sh | 35 ++++++++++++++++\n board/pc-efibootguard/post-image.sh | 7 ++++\n board/pc-efibootguard/readme.txt | 30 ++++++++++++++\n board/pc-efibootguard/run-image-qemu.sh | 9 +++++\n boot/Config.in | 2 +\n boot/efibootguard/Config.in | 37 +++++++++++++++++\n boot/efibootguard/Config.in.host | 8 ++++\n boot/efibootguard/efibootguard.hash | 3 ++\n boot/efibootguard/efibootguard.mk | 60 ++++++++++++++++++++++++++++\n configs/pc_x86_64_efibootguard_defconfig | 51 +++++++++++++++++++++++\n 13 files changed, 310 insertions(+)\n---\nbase-commit: 52ee2f5644da5389634b2465f1dc31deb5a4807c\nchange-id: 20250207-wip-obbardc-boot-efibootguard-initial-pkg-9d16e4b283fd\n\nBest regards," }
