While at it:
- Turn on hashes verification and add a hash for the Linux kernel.
- Linux kernel needs host-python3; add it.
- Convert to `make savedefconfig' format.
- Fix shellcheck warnings in our post-image script and update
.checkpackageignore.

The aarch64_efi_defconfig allows to build a minimal Linux system that can boot on all AArch64 servers providing an EFI firmware. This includes all Arm EBBR[1] compliant systems, and all Arm SystemReady[2] compliant systems for example. Building and booting ==================== $ make aarch64_efi_defconfig $ make The file output/images/disk.img is a complete disk image that can be booted, it includes the grub2 bootloader, Linux kernel and root filesystem. Testing under Qemu ================== This image can also be tested using Qemu: qemu-system-aarch64 \ -M virt \ -cpu cortex-a57 \ -m 512 \ -nographic \ -bios </path/to/QEMU_EFI.fd> \ -drive file=output/images/disk.img,if=none,format=raw,id=hd0 \ -device virtio-blk-device,drive=hd0 \ -netdev user,id=eth0 \ -device virtio-net-device,netdev=eth0 Note that </path/to/QEMU_EFI.fd> needs to point to a valid aarch64 UEFI firmware image for qemu. It may be provided by your distribution as a edk2-aarch64 or AAVMF package, in path such as /usr/share/edk2/aarch64/QEMU_EFI.fd . U-Boot based qemu firmware ========================== A qemu firmware with support for UEFI based on U-Boot can be built following the instructions in [3], with qemu_arm64_defconfig. This should give you a nor_flash.bin, which you can use with qemu as an alternative to QEMU_EFI.fd. You will also need to change the machine specification to "-M virt,secure=on" on qemu command line, to enable TrustZone support, and you will need to increase the memory with "-m 1024".
