The aarch64_efi_defconfig allows to build a minimal Linux system that
can boot on all AArch64 servers providing an EFI firmware and ACPI.

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 \
-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 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 .
