| 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. | |

| 34 | help | |
| 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. | |

| 66 | Enables support for IDE (Integrated Drive Electronics) hard drives. | |
| 67 | This allows access to raw blocks and filesystems on an IDE drive | |
| 68 | from U-Boot. See also CMD_IDE which provides an 'ide' command for | |
| 69 | performing various IDE operations. |
