[U-Boot] [PATCH v2 1/1] dm: MIGRATION: Add migration plan for CONFIG_DM

[Heinrich Schuchardt]

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.

I think we should move SPL to of-platdata and thus require DM there
also. But that requires a bit more discussion!

Applied to u-boot/master, thanks!
