I took (what I think is) the OpenEmbedded approch: generates both a
.ubifs image and a .ubi one.
We (armadeus) are most of the time using the UBI image to update our
systems from U-Boot, but I think people might be interested in having at
the same time both UBI and UBIFS images in their tftpboot directory and
know the difference by looking at the filename.
