2 bool "Support block devices"
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.
14 bool "Support SATA controllers with driver model"
17 This enables a uclass for disk controllers in U-Boot. Various driver
18 types can use this, such as AHCI/SATA. It does not provide any standard
19 operations at present. The block device interface has not been converted
23 bool "Support SATA controllers"
25 This enables support for SATA (Serial Advanced Technology
26 Attachment), a serial bus standard for connecting to hard drives and
27 other storage devices.
29 SATA replaces PATA (originally just ATA), which stands for Parallel AT
30 Attachment, where AT refers to an IBM AT (Advanced Technology)
31 computer released in 1984.
33 See also CMD_SATA which provides command-line support.
36 bool "Support SCSI controllers"
38 This enables support for SCSI (Small Computer System Interface),
39 a parallel interface widely used with storage peripherals such as
40 hard drives and optical drives. The SCSI standards define physical
41 interfaces as well as protocols for controlling devices and
45 bool "Support SCSI controllers with driver model"
48 This option enables the SCSI (Small Computer System Interface) uclass
49 which supports SCSI and SATA HDDs. For every device configuration
50 (IDs/LUNs) a block device is created with RAW read/write and
54 bool "Use block device cache"
57 This option enables a disk-block cache for all block devices.
58 This is most useful when accessing filesystems under U-Boot since
59 it will prevent repeated reads from directory structures and other
60 filesystem data structures.
62 menu "SATA/SCSI device support"
65 bool "Ceva Sata controller"
69 This option enables Ceva Sata controller hard IP available on Xilinx
70 ZynqMP. Support up to 2 external devices. Complient with SATA 3.1 and
71 AHCI 1.3 specifications with hot-plug detect feature.
75 bool "Enable Synopsys DWC AHCI driver support"
80 Enable this driver to support Sata devices through
81 Synopsys DWC AHCI module.
86 bool "Support IDE controllers"
88 Enables support for IDE (Integrated Drive Electronics) hard drives.
89 This allows access to raw blocks and filesystems on an IDE drive
90 from U-Boot. See also CMD_IDE which provides an 'ide' command for
91 performing various IDE operations.
