-	  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.
+	  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.

+	default y
+	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.

+config IDE

+	help
+	  Enables support for IDE (Integrated Drive Electronics) hard drives.
+	  This allows access to raw blocks and filesystems on an IDE drive
+	  from U-Boot. See also CMD_IDE which provides an 'ide' command for
+	  performing various IDE operations.
