| default y if DM_MMC | |
| help | |
| Enable support for block devices, such as SCSI, MMC and USB | |
| flash sticks. These provide a block-level interface which permits | |
| reading, writing and (in some cases) erasing blocks. Block | |
| devices often have a partition table which allows the device to | |
| be partitioned into several areas, called 'partitions' in U-Boot. | |
| A filesystem can be placed in each partition. | |
| config AHCI | |

| depends on DM | |
| help | |
| This enables a uclass for disk controllers in U-Boot. Various driver | |
| types can use this, such as AHCI/SATA. It does not provide any standard | |
| operations at present. The block device interface has not been converted | |
| to driver model. | |
| config DM_SCSI | |
| bool "Support SCSI controllers with driver model" | |
| depends on BLK | |
| help | |
| This option enables the SCSI (Small Computer System Interface) uclass | |
| which supports SCSI and SATA HDDs. For every device configuration | |
| (IDs/LUNs) a block device is created with RAW read/write and | |
| filesystem support. | |
| config BLOCK_CACHE | |
| bool "Use block device cache" | |
| default n | |
| help | |
| This option enables a disk-block cache for all block devices. | |
| This is most useful when accessing filesystems under U-Boot since | |
| it will prevent repeated reads from directory structures and other | |
| filesystem data structures. | |
