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

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

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