   5         help
   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.

  13 config AHCI

  15         depends on DM
  16         help
  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.

  22 config DM_SCSI
  23         bool "Support SCSI controllers with driver model"
  24         depends on BLK
  25         help
  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.

  31 config BLOCK_CACHE
  32         bool "Use block device cache"
  33         default n
  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.

  47           This option enables Ceva Sata controller hard IP available on Xilinx
  48           ZynqMP. Support up to 2 external devices. Complient with SATA 3.1 and
  49           AHCI 1.3 specifications with hot-plug detect feature.
