This one's been around long enough that I'm going to add
it to target-arm.next now.

There were previously questions about whether we should
have flash or RAM at the bottom, but I think it makes
sense just to have a "like vexpress" config with two
flash devices. This does make telling QEMU about backing
storage for the 2nd flash a little complicated, but I
think anybody seriously running a config like that will
be using the management tools layer anyhow.
