   4         default y if DM_MMC
   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.
  21
  22 config SATA
  23         bool "Support SATA controllers"
  24         help
  25           This enables support for SATA (Serial Advanced Technology
  26           Attachment), a serial bus standard for connecting to hard drives and
  27           other storage devices.
  28
  29           SATA replaces PATA (originally just ATA), which stands for Parallel AT
  30           Attachment, where AT refers to an IBM AT (Advanced Technology)
  31           computer released in 1984.
  32
  33           See also CMD_SATA which provides command-line support.

  35 config SCSI
  36         bool "Support SCSI controllers"
  37         help
  38           This enables support for SCSI (Small Computer System Interface),
  39           a parallel interface widely used with storage peripherals such as
  40           hard drives and optical drives. The SCSI standards define physical
  41           interfaces as well as protocols for controlling devices and
  42           tranferring data.

  44 config DM_SCSI
  45         bool "Support SCSI controllers with driver model"
  46         depends on BLK
  47         help
  48           This option enables the SCSI (Small Computer System Interface) uclass
  49           which supports SCSI and SATA HDDs. For every device configuration
  50           (IDs/LUNs) a block device is created with RAW read/write and
  51           filesystem support.

  53 config BLOCK_CACHE
  54         bool "Use block device cache"
  55         default n
  56         help
  57           This option enables a disk-block cache for all block devices.
  58           This is most useful when accessing filesystems under U-Boot since
  59           it will prevent repeated reads from directory structures and other
  60           filesystem data structures.

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

  85 config IDE
  86         bool "Support IDE controllers"
  87         help
  88           Enables support for IDE (Integrated Drive Electronics) hard drives.
  89           This allows access to raw blocks and filesystems on an IDE drive
  90           from U-Boot. See also CMD_IDE which provides an 'ide' command for
  91           performing various IDE operations.
