This option is fact really related to SPL. For U-Boot proper we always use driver model for block devices, so CONFIG_BLK is enabled if block devices are in use. It is only for SPL that we have two cases: - SPL_BLK is enabled, in which case we use driver model and blk-uclass.c - SPL_BLK is not enabled, in which case (if we need block devices) we must use blk_legacy.c Rename the symbol to SPL_LEGACY_BLOCK to make this clear. This is different enough from BLK and SPL_BLK that there should be no confusion. Signed-off-by: Simon Glass <sjg@chromium.org>

This enables support for SCSI (Small Computer System Interface),
|
|
a parallel interface widely used with storage peripherals such as
|
|
hard drives and optical drives. The SCSI standards define physical
|
|
interfaces as well as protocols for controlling devices and
|
|
tranferring data.

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.

This enables a way for boards to set up an AHCI device manually, by

called ahci_init() and providing an ahci_reset() mechanism.

This is deprecated. An AHCI driver should be provided instead.
