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 Signed-off-by: Niklas Cassel <niklas.cassel@wdc.com> Signed-off-by: Damien Le Moal <damien.lemoal@opensource.wdc.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>
