- 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.
