hw/arm: add static NVDIMMs in device tree
NVDIMM is used for fast rootfs with EROFS, for example by kata containers. To allow booting with static NVDIMM memory, add them to the device tree in arm virt machine. This allows users to boot directly with nvdimm memory devices without having to rely on ACPI and hotplug. Verified to work with command invocation: ./qemu-system-aarch64 \ -M virt,nvdimm=on \ -cpu cortex-a57 \ -m 4G,slots=2,maxmem=8G \ -object memory-backend-file,id=mem1,share=on,mem-path=/tmp/nvdimm,size=4G,readonly=off \ -device nvdimm,id=nvdimm1,memdev=mem1,unarmed=off \ -drive file=./debian-12-nocloud-arm64-commited.qcow2,format=qcow2 \ -kernel ./vmlinuz-6.1.0-13-arm64 \ -append "root=/dev/vda1 console=ttyAMA0,115200 acpi=off" -initrd ./initrd.img-6.1.0-13-arm64 \ -nographic \ -serial mon:stdio Signed-off-by: Manos Pitsidianakis <manos.pitsidianakis@linaro.org> Message-id: 20250807-nvdimm_arm64_virt-v2-1-b8054578bea8@linaro.org Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
