5 | help |
6 | Enable support for block devices, such as SCSI, MMC and USB | |
7 | flash sticks. These provide a block-level interface which permits | |
8 | reading, writing and (in some cases) erasing blocks. Block | |
9 | devices often have a partition table which allows the device to | |
10 | be partitioned into several areas, called 'partitions' in U-Boot. | |
11 | A filesystem can be placed in each partition. | |

25 | config BLOCK_CACHE |
26 | bool "Use block device cache" | |
27 | default n | |
28 | help | |
29 | This option enables a disk-block cache for all block devices. | |
30 | This is most useful when accessing filesystems under U-Boot since | |
31 | it will prevent repeated reads from directory structures and other | |
32 | filesystem data structures. | |

34 | config IDE |
35 | bool "Support IDE controllers" | |
36 | help | |
37 | Enables support for IDE (Integrated Drive Electronics) hard drives. | |
38 | This allows access to raw blocks and filesystems on an IDE drive | |
39 | from U-Boot. See also CMD_IDE which provides an 'ide' command for | |
40 | performing various IDE operations. | |

42 | config SYSTEMACE | |
43 | bool "Xilinx SystemACE support" | |
44 | help | |
45 | Adding this option adds support for Xilinx SystemACE chips attached | |
46 | via some sort of local bus. The address of the chip must also be | |
47 | defined in the CONFIG_SYS_SYSTEMACE_BASE macro. | |
48 | ||
49 | When SystemACE support is added, the "ace" device type becomes | |
50 | available to the fat commands, i.e. fatls. | |
