dm: Add migration plan for CONFIG_BLK The CONFIG_BLK conversion involves quite invasive changes in the U-Boot code, with #ifdefs and different code paths. We should try to move over to this soon so we can drop the old code. Set a deadline of 9 months for this work, rounded up to the next release.

Migration Schedule
====================
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 DM_MMC Given that at this point the MMC subsystem itself has been migrated along with a number of subsystem drivers, formalize a deadline for migration.

CONFIG_DM_MMC
-------------
Status: In progress
Deadline: 2019.04
The subsystem itself has been converted and maintainers should submit patches
switching over to using CONFIG_DM_MMC and other base driver model options in
time for inclusion in the 2019.04 rerelease.

In concert with maintainers migrating their block device usage to the
appropriate DM driver, CONFIG_BLK needs to be set as well. The final deadline
here coincides with the final deadline for migration of the various block
blk: Rework guard around part_init call The function part_init() will only be built when we have both CONFIG_PARTITIONS and CONFIG_HAVE_BLOCK_DEVICE set.
