   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.

  25 config BLOCK_CACHE
  26         bool "Use block device cache"
  27         default n
  28         help
  29           This option enables a disk-block cache for all block devices.
  30           This is most useful when accessing filesystems under U-Boot since
  31           it will prevent repeated reads from directory structures and other
  32           filesystem data structures.
  33
  34 config IDE
  35         bool "Support IDE controllers"
  36         help
  37           Enables support for IDE (Integrated Drive Electronics) hard drives.
  38           This allows access to raw blocks and filesystems on an IDE drive
  39           from U-Boot. See also CMD_IDE which provides an 'ide' command for
  40           performing various IDE operations.

  42 config SYSTEMACE
  43         bool "Xilinx SystemACE support"
  44         help
  45           Adding this option adds support for Xilinx SystemACE chips attached
  46           via some sort of local bus. The address of the chip must also be
  47           defined in the CONFIG_SYS_SYSTEMACE_BASE macro.
  48
  49           When SystemACE support is added, the "ace" device type becomes
  50           available to the fat commands, i.e. fatls.
