| config BLK |
| bool "Support block devices" |
| depends on DM |
| 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 |
| bool "Support SATA controllers with driver model" |
| 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. |

| ZynqMP. Support up to 2 external devices. Complient with SATA 3.1 and |
