+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.
+
+CONFIG_DM
+---------
+
+* Status: In progress
+* Deadline: 2020.01
+
+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.
+
+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.
+
+CONFIG_DM_USB
+-------------
+
+* Status: In progress
+* Deadline: 2019.07
+
+The subsystem itself has been converted along with many of the host controller
+and maintainers should submit patches switching over to using CONFIG_DM_USB and
+other base driver model options in time for inclusion in the 2019.07 rerelease.
+
+CONFIG_SATA
+-----------
+
+* Status: In progress
+* Deadline: 2019.07
+
+The subsystem itself has been converted along with many of the host controller
+and maintainers should submit patches switching over to using CONFIG_AHCI and
+other base driver model options in time for inclusion in the 2019.07 rerelease.
+
+CONFIG_BLK
+----------
+
+* Status: In progress
+* Deadline: 2019.07
+
+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
+subsystems.  At this point we will be able to audit and correct the logic in
+Kconfig around using CONFIG_PARTITIONS and CONFIG_HAVE_BLOCK_DEVICE and make
+use of CONFIG_BLK / CONFIG_SPL_BLK as needed.
+
+CONFIG_DM_SPI / CONFIG_DM_SPI_FLASH
+-----------------------------------
+
+Board Maintainers should submit the patches for enabling DM_SPI and DM_SPI_FLASH
+to move the migration with in the deadline.
+
+Partially converted::
+
+	drivers/spi/fsl_espi.c
+	drivers/spi/mxc_spi.c
+	drivers/spi/sh_qspi.c
+
+* Status: In progress
+* Deadline: 2019.07
+
+CONFIG_DM_PCI
+-------------
+Deadline: 2019.07
+
+The PCI subsystem has supported driver model since mid 2015. Maintainers should
+submit patches switching over to using CONFIG_DM_PCI and other base driver
+model options in time for inclusion in the 2019.07 release.
+
+
+CONFIG_DM_VIDEO
+---------------
+Deadline: 2019.07
+
+The video subsystem has supported driver model since early 2016. Maintainers
+should submit patches switching over to using CONFIG_DM_VIDEO and other base
+driver model options in time for inclusion in the 2019.07 release.
+
+CONFIG_DM_ETH
+-------------
+Deadline: 2020.07
+
+The network subsystem has supported the driver model since early 2015.
+Maintainers should submit patches switching over to using CONFIG_DM_ETH and
+other base driver model options in time for inclusion in the 2020.07 release.
