1config BLK
2	bool "Support block devices"
3	depends on DM
4	help
5	  Enable support for block devices, such as SCSI, MMC and USB
6	  flash sticks. These provide a block-level interface which permits
7	  reading, writing and (in some cases) erasing blocks. Block
8	  devices often have a partition table which allows the device to
9	  be partitioned into several areas, called 'partitions' in U-Boot.
10	  A filesystem can be placed in each partition.

12config AHCI
13	bool "Support SATA controllers with driver model"
14	depends on DM
15	help
16	  This enables a uclass for disk controllers in U-Boot. Various driver
17	  types can use this, such as AHCI/SATA. It does not provide any standard
18	  operations at present. The block device interface has not been converted
19	  to driver model.

21config BLOCK_CACHE
22	bool "Use block device cache"
23	default n
24	help
25	  This option enables a disk-block cache for all block devices.
26	  This is most useful when accessing filesystems under U-Boot since
27	  it will prevent repeated reads from directory structures and other
28	  filesystem data structures.
