Sure it is not up to me to take the decision. But I would like to get
the opinion-forming started.

We have discussed on the dev list that we should strive to move
partitions to the driver model and to provide a better integration
between the drivers and the UEFI sub-system. CONFIG_DM=y is one of the
prerequisites.

Since more than a year all maintainers are urged to move to DM_MMC,
DM_USB, DM_SATA, etc. See doc/driver-model/migration.rst. These all
require that DM is enabled. The maintainers of the boards concerned are
on copy.
