It doesn't seem to fix the issue if the partition data is in devicetree.

Here is my sample qemu command line:

qemu-system-arm -M supermicro-x11spi-bmc,fmc-model=n25q256a13,spi-model=n25q256a13 \
	-kernel arch/arm/boot/zImage -no-reboot \
	-snapshot -audio none \
	-drive file=/tmp/flash,format=raw,if=mtd \
	-drive file=/tmp/flash,format=raw,if=mtd,index=1 \
	-nic user \
	--append "kunit.enable=0 root=/dev/mtdblock0 rootwait console=ttyS4,115200 earlycon=uart8250,mmio32,0x1e784000,115200n8" \
	-dtb arch/arm/boot/dts/aspeed/aspeed-bmc-supermicro-x11spi.dtb \
	-nographic -monitor null -serial stdio

This does not create any mtd partitions, even after applying the
patch suggested earlier.
