Niklas Cassel 1b298db82f configs/qemu_riscv64_nommu_virt_defconfig: new defconfig
Add RISC-V 64-bit nommu defconfig for QEMU virt machine with MMU
disabled.

Unlike qemu_riscv64_virt, qemu_riscv64_nommu_virt does not use OpenSBI,
since the kernel is running in machine mode (M-mode).

After the build is complete, you can start QEMU using the launcher
script:
$ output/images/start-qemu.sh

Run Linux in emulation with:

  qemu-system-riscv64 -M virt -bios output/images/fw_jump.elf -kernel output/images/Image -append "rootwait root=/dev/vda ro" -drive file=output/images/rootfs.ext2,format=raw,id=hd0 -device virtio-blk-device,drive=hd0 -netdev user,id=net0 -device virtio-net-device,netdev=net0 -nographic # qemu_riscv64_virt_defconfig

  qemu-system-riscv64 -M virt -bios none -kernel output/images/Image -append "rootwait root=/dev/vda ro" -drive file=output/images/rootfs.ext2,format=raw,id=hd0 -device virtio-blk-device,drive=hd0 -nographic -cpu rv64,mmu=off # qemu_riscv64_nommu_virt_defconfig

The login prompt will appear in the terminal that started Qemu.
