[U-Boot] [RFC] enforce CONFIG_DM=y

[Heinrich Schuchardt]

The time lines set force in doc/driver-model/migration.rst for different
subsystems to move to the driver model have been passed.

I ran a test on Travis CI
https://travis-ci.org/xypron2/u-boot/builds/569776600
that showed only 8 boards remain that cannot be built with CONFIG_DM=y.

H2200
* h2200

Renesas
* sh7757lcr
* sh7752evb
* r2dplus
* sh7753evb
* sh7763rdp
* MigoR
* r7780mp.

I think it is time that we enforce CONFIG_DM=y in U-Boot and remove
boards that do not support it.

Best regards

Heinrich

Agreed, that is a small list. I think Tom should make the call though.

Was there ever a warning about this , to notify the maintainers that the
boards need conversion ?

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.

I think for H2200 we talked about dropping that during the last "can we
find a newer toolchain for everyone?" thread, and I'll check my email
again on that.  For the SH boards, you and I had a conversation about
them awhile ago that lead to you removing a number of platforms, so
those are the ones that are left that need converting or dropping.

I agree that H2200 board should be removed from main Das U-Boot tree.
I don't have enough time to support it correctly (to keep up with 
development of whole project).

So I was asked to retain migor and r2dplus. I need some time to figure
out the details of what will really be retained. When are they due to be
dropped ?

The boards above are the ones that cannot be built with DM=y. Others may
be failing at runtime. Therefore I suggest targeting the v2020.01
release.  If that date is ok, let's add a warning via /Makefile:

"This board does not use CONFIG_DM=y. All boards without CONFIG_DM=y
will be removed from U-Boot with the v2020.01 release."

That's fine I think.

I am somewhat concerned that enforcing the overhead of DM on everyone
might make U-Boot less "universal".

Do you have some suggestions on how to improve the situation?
