Subject: [RFC PATCH 19/21] DO_NOT_MERGE riscv: dts: qemu: add dump from riscv-cbqri-rfc
Dumped dtb from qemu branch riscv-cbqri-rfc which is on top of qemu
master (tag: v8.0.0-rc4) with qemu/VERSION of 7.2.94 invoked with:
qemu-system-riscv64 \
-M virt \
-nographic \
-smp 8 \
-bios output/images/fw_jump.elf \
-kernel $HOME/kernel/cbqri-linux/arch/riscv/boot/Image \
-append "root=/dev/vda ro" \
-drive file=output/images/rootfs.ext2,format=raw,id=hd0 \
-device virtio-blk-device,drive=hd0 \
-machine dumpdtb=qemu.dtb

Note: this is necessary as Qemu branch riscv-cbqri-rfc does not yet
support generating a dtb with the nodes and properties needed for CBQRI
controllers. Thus, those lines must be added in the next patch and an
external dtb (qemu-virt-cbqri.dtb) built by Linux is used when
invoking qemu-system-riscv64
