config BLK
bool "Support block devices"
depends on DM
default y if DM_MMC
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.
config AHCI
bool "Support SATA controllers with driver model"
depends on DM
help
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.
config DM_SCSI
bool "Support SCSI controllers with driver model"
depends on BLK
help
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.
config BLOCK_CACHE
bool "Use block device cache"
default n
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 SATA_CEVA
bool "Ceva Sata controller"
depends on AHCI
depends on DM_SCSI
help
This option enables Ceva Sata controller hard IP available on Xilinx
ZynqMP. Support up to 2 external devices. Complient with SATA 3.1 and
AHCI 1.3 specifications with hot-plug detect feature.
