At present we have the SCSI drivers in the drivers/block and common/ directories. It is better to split them out into their own place. Use drivers/scsi which is what Linux does. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

help
|
|
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.

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.

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.
