   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.
  12
  13 config HAVE_BLOCK_DEVICE
  14         bool "Enable Legacy Block Device"
  15         help
  16           Some devices require block support whether or not DM is enabled

  18 config SPL_BLK
  19         bool "Support block devices in SPL"
  20         depends on SPL_DM && BLK
  21         default y

  24           flash sticks. These provide a block-level interface which permits

  30 config BLOCK_CACHE
  31         bool "Use block device cache"
  32         default n
  33         help
  34           This option enables a disk-block cache for all block devices.
  35           This is most useful when accessing filesystems under U-Boot since
  36           it will prevent repeated reads from directory structures and other
  37           filesystem data structures.

  39 config IDE
  40         bool "Support IDE controllers"
  41         select HAVE_BLOCK_DEVICE
  42         help
  43           Enables support for IDE (Integrated Drive Electronics) hard drives.
  44           This allows access to raw blocks and filesystems on an IDE drive
  45           from U-Boot. See also CMD_IDE which provides an 'ide' command for
  46           performing various IDE operations.

  48 config SYSTEMACE
  49         bool "Xilinx SystemACE support"
  50         select HAVE_BLOCK_DEVICE
  51         help
  52           Adding this option adds support for Xilinx SystemACE chips attached
  53           via some sort of local bus. The address of the chip must also be
  54           defined in the CONFIG_SYS_SYSTEMACE_BASE macro.
  55
  56           When SystemACE support is added, the "ace" device type becomes
  57           available to the fat commands, i.e. fatls.
  58
  59 config SYS_SYSTEMACE_BASE
  60         hex "Base address of SystemACE chip"
  61         depends on SYSTEMACE
  62
  63 config SYS_SYSTEMACE_WIDTH
  64         int "Word size of access to the of SystemACE chip"
  65         depends on SYSTEMACE
