I don't think so, generally not specifying something means that it won't be loaded (-bios is just odd for historical reasons). Maybe just a log warning like "The QEMU Icicle machine does not generate a device tree, so no device tree is being provided to the guest". It'll be a bit annoying for people who don't want to run Linux (like your case), but all other Linux class RISC-V boards provide a DTB, so it's a little confusing Alistair > > -- > embedded brains GmbH & Co.
