The Qemu ARM64 Virt platform has a memory-mapped flash starting at physical address 0. This clashes with the zero page used to trap NULL pointer accesses when MMU is enabled. For this reason, qemu_virt64_defconfig disabled the MMU. qemu_virt64_defconfig was removed in favor of multi_v8_defconfig, but the latter enables the MMU, breaking the ability to test barebox environment and state out of the box. Another pitfall of multi_v8_defconfig is that it requires firmware to build. Until there's a way to: make $defconfig make result in a working QEMU Virt64 image, we should not drop the qemu_virt64_defconfig file. We import here the last version with CONFIG_MTD_CONCAT=y enabled.
