+This little documentation explain how to build a kernel and a rootfs for qemu with sh4 architecture.
+
+1) Select qemu sh4 configuration and compile it :
+
+make sh4_defconfig
+make all
+
+2) Run qemu-system-sh4 with the kernel and rootfs previously generated
+
+It's recommanded to use a git release for qemu (stable version don't have a nice output).
+If you want to avoid building all target, you can use this option on qemu configure : --target-list=sh4-softmmu
+
+The command is :
+qemu-system-sh4 -M r2d -kernel output/images/zImage -drive file=output/images/rootfs.ext2,if=ide,format=raw -append root=/dev/sda console=ttySC1,115200 noiotrap
