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.

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.

26 This option enables the SCSI (Small Computer System Interface) uclass
27 which supports SCSI and SATA HDDs. For every device configuration
28 (IDs/LUNs) a block device is created with RAW read/write and
29 filesystem support.

35 This option enables a disk-block cache for all block devices.
36 This is most useful when accessing filesystems under U-Boot since
37 it will prevent repeated reads from directory structures and other
38 filesystem data structures.
