At present CONFIG_CMD_SATA enables the 'sata' command which also brings in SATA support. Some boards may wish to enable SATA without the command. Add a separate CONFIG to permit this. 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.

|

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.

bool "Support SATA controllers"
|
|
help
|
|
This enables support for SATA (Serial Advanced Technology
|
|
Attachment), a serial bus standard for connecting to hard drives and
|
|
other storage devices.
|
|
|
|
SATA replaces PATA (originally just ATA), which stands for Parallel AT
|
|
Attachment, where AT refers to an IBM AT (Advanced Technology)
|
|
computer released in 1984.
|
|
|
|
See also CMD_SATA which provides command-line support.

bool "Support SCSI controllers"
|
|
help
|
|
This enables support for SCSI (Small Computer System Interface),
|
|
a parallel interface widely used with storage peripherals such as
|
|
hard drives and optical drives. The SCSI standards define physical
|
|
interfaces as well as protocols for controlling devices and
|
|
tranferring data.

|

This option enables the SCSI (Small Computer System Interface) uclass
|
|
which supports SCSI and SATA HDDs. For every device configuration
|
|
(IDs/LUNs) a block device is created with RAW read/write and
|
|
filesystem support.

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.
