+Root file system on flash drive
+-------------------------------
+
+Rather than using a root file system on ram disk, it is possible to have it on
+CFI flash. Given an ext2 image whose size must be a power of two, it can be used
+as follows:

+.. code-block:: bash

+ $ qemu-system-ppc64 -M ppce500 -cpu e500mc -smp 4 -m 2G \
+ -display none -serial stdio \
