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.

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

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.

config SYSTEMACE

bool "Xilinx SystemACE support"
|
|
select HAVE_BLOCK_DEVICE
|
|
help
|
|
Adding this option adds support for Xilinx SystemACE chips attached
|
|
via some sort of local bus. The address of the chip must also be
|
|
defined in the CONFIG_SYS_SYSTEMACE_BASE macro.
|
|
|
|
When SystemACE support is added, the "ace" device type becomes
|
|
available to the fat commands, i.e. fatls.
