Tom Rini 34a5c4257a SystemACE: Remove
This driver is no longer used on any supported platform in U-Boot and
there is no interest in maintaining it further from people that have
used it historically.

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 HAVE_BLOCK_DEVICE
bool "Enable Legacy Block Device"
help
Some devices require block support whether or not DM is enabled
config SPL_BLK
bool "Support block devices in SPL"
depends on SPL_DM && BLK
default y
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 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 IDE
bool "Support IDE controllers"
select HAVE_BLOCK_DEVICE
help
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.
