Hello,

This commit was doing two fairly unrelated things: adding the
bootloader preparation script, and adding the genimage template, so
I've split this commit into two, and applied to master. Thanks!

Thinking more about this, perhaps moving forward we will want to do
this in the U-Boot package directly. But I'd like to wait and see how
mainline U-Boot will handle i.MX8 platforms in terms of image creation.
