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.
13 config HAVE_BLOCK_DEVICE
14 bool "Enable Legacy Block Device"
16 Some devices require block support whether or not DM is enabled
19 bool "Support block devices in SPL"
20 depends on SPL_DM && BLK
23 Enable support for block devices, such as SCSI, MMC and USB
24 flash sticks. These provide a block-level interface which permits
25 reading, writing and (in some cases) erasing blocks. Block
26 devices often have a partition table which allows the device to
27 be partitioned into several areas, called 'partitions' in U-Boot.
28 A filesystem can be placed in each partition.
31 bool "Use block device cache"
35 This option enables a disk-block cache for all block devices.
36 This is most useful when accessing filesystems under U-Boot since
37 it will prevent repeated reads from directory structures and other
38 filesystem data structures.
41 bool "Support IDE controllers"
42 select HAVE_BLOCK_DEVICE
44 Enables support for IDE (Integrated Drive Electronics) hard drives.
45 This allows access to raw blocks and filesystems on an IDE drive
46 from U-Boot. See also CMD_IDE which provides an 'ide' command for
47 performing various IDE operations.
