Tom Rini7cfc1a32018-11-29 18:21:14 -0500[diff] [blame]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
Tom Rini91ff6862018-12-05 08:23:38 -0500[diff] [blame]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.
