[PATCH 11/35] RFC: efi: Drop code that doesn't work with driver model
Simon Glass
sjg at chromium.org
Wed Sep 8 15:33:41 CEST 2021
This code should never have been added as it builds a new feature on top
of legacy code. Drop it and add a dependency on BLK for this feature.
Boards which want EFI_LOADER should migrate to driver model first.
