Hey all, One problem we have today is how the BLK symbol is set and used in Kconfig files. Part of the challenge is that we use it as a gating symbol for "we have a block device" and also for "enable block device library code". What this series does is move to always use "select BLK" by block drivers (a few were and a few others had it the inverse) and then "depends on BLK" for functionality that needs a block device present. The end result of this series is that a number of platforms which had disabled EFI_LOADER now don't ask for it (they have no block device) and espresso7420 has a regression about MMC support fixed.
