Changes

See the [https://www.qemu.org/docs/master/system/target-arm.html Arm System Emulator]] documentation on the QEMU web site for details on optional arguments which can be used to specify machine type, SVE/SVE2 vector length, and so forth. Note that qemu-aarch64 does not differentiate between SVE and SVE2 (at the time of writing, it is not possible to enable SVE without enabling SVE2).
