Unfortunately, we cannot do this because it introduces incompatibility
(data loss) for users who may have some data stored in "free space".

I should have insisted on a lot of padding for the u-boot partition or
asked not to add partitions to DT at all. For now the only solution is
to use command line partitions. They take precedence over DT partitions.

Thanks,
