[Buildroot] grub/grub2 support on AARCH64 native compilation

[Saxena, Nitin]

Thanks baruch.

I need a way to get VM image for aarch64 via buildroot (native compilation) so that I can launch it via qemu-system-aarch64.
I tried compiling buildroot-2017.05.2 and got rootfs.tar and kernel "Image". I created ext4 file system from rootfs.tar and tried to launch QEMU using following command

=============
T=/home/dut/launch/br
qemu-system-aarch64 -enable-kvm -m 2048 -smp 4 -cpu host \
    -M virt,gic_version=3 -nographic \
    -kernel $T/Image --append "console=ttyAMA0 root=/dev/vda rw"  \
    -drive file=$T/rootfs.img,if=virtio,aio=threads \
    -netdev user,id=user0 -device virtio-net,netdev=user0
=============

Is this possible with buildroot package? I can try latest buildroot package.

Thanks,
Nitin

The grub/grub2 packages in Buildroot only support x86 targets at the moment.
