| 6 | U-Boot has been migrating to a new driver model since its introduction in |
| 7 | 2014. This file describes the schedule for deprecation of pre-driver-model |
| 8 | features. |

| 15 | |
| 16 | Starting with the 2010.01 release CONFIG_DM will be enabled for all boards. |
| 17 | This does not concern CONFIG_DM_SPL and CONFIG_DM_TPL. The conversion date for |
| 18 | these configuration items still needs to be defined. |

| 26 | The subsystem itself has been converted and maintainers should submit patches |
| 27 | switching over to using CONFIG_DM_MMC and other base driver model options in |
| 28 | time for inclusion in the 2019.04 rerelease. |

| Tom Rini | efacd9f | 2018-11-29 18:21:14 -0500 | [diff] [blame] | 56 | In concert with maintainers migrating their block device usage to the |
| 57 | appropriate DM driver, CONFIG_BLK needs to be set as well. The final deadline |
| 58 | here coincides with the final deadline for migration of the various block |
| Tom Rini | 1794ae6 | 2018-12-05 08:23:38 -0500 | [diff] [blame] | 59 | subsystems. At this point we will be able to audit and correct the logic in |
| 60 | Kconfig around using CONFIG_PARTITIONS and CONFIG_HAVE_BLOCK_DEVICE and make |
| 61 | use of CONFIG_BLK / CONFIG_SPL_BLK as needed. |
