config BLK
bool "Support block devices"
depends on DM
help
Enable support for block devices, such as SCSI, MMC and USB
flash sticks. These provide a block-level interface which permits
reading, writing and (in some cases) erasing blocks. Block
devices often have a partition table which allows the device to
be partitioned into several areas, called 'partitions' in U-Boot.
A filesystem can be placed in each partition.
config DISK
bool "Support disk controllers with driver model"
depends on DM
default y if DM
help
This enables a uclass for disk controllers in U-Boot. Various driver
types can use this, such as AHCI/SATA. It does not provide any standard
operations at present. The block device interface has not been converted
to driver model.
