2 bool "Support block devices"
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.
14 bool "Use block device cache"
17 This option enables a disk-block cache for all block devices.
18 This is most useful when accessing filesystems under U-Boot since
19 it will prevent repeated reads from directory structures and other
20 filesystem data structures.
23 bool "Support IDE controllers"
25 Enables support for IDE (Integrated Drive Electronics) hard drives.
26 This allows access to raw blocks and filesystems on an IDE drive
27 from U-Boot. See also CMD_IDE which provides an 'ide' command for
28 performing various IDE operations.
