I am working on converting sunxi target to using new image generation
code.  The initial goal is just that preserving what the current code
does, i.e. making fix-sized sdcard images.

I'd like to add another type of image where we have read-only squashfs
rootfs and mkfs.ext4 remaining space at firstboot and using that ext4
fs as rw overlay.  This part may take a while to review and evolve
though and as such may not catch up with the release schedule.
