U-Boot has been migrating to a new driver model since its introduction in
2014. This file describes the schedule for deprecation of pre-driver-model
features.
dm: MIGRATION: Add migration plan for CONFIG_DM For many sub-systems we already require the driver model to be used. Yet there is still a handful of boards that do not have CONFIG_DM enabled. We should make CONFIG_DM compulsory with release v2020.01 Conversion dates for CONFIG_DM_SPL and CONFIG_DM_TPL are yet to be defined.

Starting with the 2010.01 release CONFIG_DM will be enabled for all boards.
This does not concern CONFIG_DM_SPL and CONFIG_DM_TPL. The conversion date for
these configuration items still needs to be defined.
