This is mostly based on the existing qemu-generic-arm64 machine, but by not being based on the genericarm64 and instead being specifically a machine to run on the qemu sbsa-ref machine we get to tune differently. Specifically, this configures sbsa-ref to be a Neoverse N2 (v9), and the tune is set to match. Another notable difference to qemu-generic-arm64 is that the kernel configuration is at present defconfig. We may wish to change this in the future to be the same fragmented configuration as genericarm64. We have to ignore two testimage parselogs failures: one from NUMA which will be fixed in a future EDK2 release, and one from efifb where we should be using the bochsdrm driver instead (further investigation is needed) Signed-off-by: Ross Burton <ross.burton@arm.com> Signed-off-by: Jon Mason <jon.mason@arm.com>
