Currently, development on arm64 is aided by a Foundation_v8 emulator
distributed by ARM [1]. To run their kernels, users will execute:
$ ./Foundation_v8 --image linux-system.axf --block-device raring-rootfs
To mount the raring-rootfs filesystem, the kernel parameter should
typically include:
root=/dev/vda
For this device to be present, the kernel must be compiled with
VIRTIO_{MMIO,BLK}. To make this work out-of-the-box, make it part of the
default configuration.
