We also need to cover:

uImage     | raw  | nand   | 0       | "kernel" | "-"  | "-"   | "-"   |

Since partitions provide start/size.  And I'm not totally sure we're
providing enough information for 'destination resides in this part of
UBI container'.  It could be "/boot/uImage in rootfs in ubi0" or "raw to
kernel0 in ubi0".
