1Migration Schedule
2====================
3
4U-Boot has been migrating to a new driver model since its introduction in
52014. This file describes the schedule for deprecation of pre-driver-model
6features.
7
8CONFIG_DM_MMC
9-------------
10
11Status: In progress
12Deadline: 2019.04
13
14The subsystem itself has been converted and maintainers should submit patches
15switching over to using CONFIG_DM_MMC and other base driver model options in
16time for inclusion in the 2019.04 rerelease.
17
18CONFIG_DM_USB
19-------------
20
21Status: In progress
22Deadline: 2019.07
23
24The subsystem itself has been converted along with many of the host controller
25and maintainers should submit patches switching over to using CONFIG_DM_USB and
26other base driver model options in time for inclusion in the 2019.07 rerelease.
27
28CONFIG_SATA
29-----------
30
31Status: In progress
32Deadline: 2019.07
33
34The subsystem itself has been converted along with many of the host controller
35and maintainers should submit patches switching over to using CONFIG_AHCI and
36other base driver model options in time for inclusion in the 2019.07 rerelease.
37
38CONFIG_BLK
39----------
40
41Status: In progress
42Deadline: 2019.07
43
44In concert with maintainers migrating their block device usage to the
45appropriate DM driver, CONFIG_BLK needs to be set as well.  The final deadline
46here coincides with the final deadline for migration of the various block
47subsystems.  At this point we will be able to audit and correct the logic in
48Kconfig around using CONFIG_PARTITIONS and CONFIG_HAVE_BLOCK_DEVICE and make
49use of CONFIG_BLK / CONFIG_SPL_BLK as needed.
50
51CONFIG_DM_SPI
52CONFIG_DM_SPI_FLASH
53-------------------
54
55Board Maintainers should submit the patches for enabling DM_SPI and DM_SPI_FLASH
56to move the migration with in the deadline.
