| 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. |
