+Testing NVMe with QEMU x86
+--------------------------
+QEMU supports NVMe emulation and we can test NVMe driver with QEMU x86 running
+U-Boot. Please see README.x86 for how to build u-boot.rom image for QEMU x86.
+
+Example command line to call QEMU x86 below with emulated NVMe device:
+$ ./qemu-system-i386 -drive file=nvme.img,if=none,id=drv0 -device nvme,drive=drv0,serial=QEMUNVME0001 -bios u-boot.rom
