menuconfig RT_USING_ATA
bool "Using Advanced Technology Attachment (ATA) device drivers"
depends on RT_USING_DM
depends on RT_USING_BLK
depends on RT_USING_DMA
default n
help
Enable the ATA core so AHCI/legacy controllers can register themselves in
the driver model, allocate DMA resources, and expose block devices to the
RT-Thread block layer. Select this only on SoCs/boards that actually wire
SATA ports because it pulls in the SCSI translation layer and requires DMA
support. When disabled, no SATA disks will be enumerated.
config RT_ATA_AHCI
bool "Advanced Host Controller Interface (AHCI)"
depends on RT_USING_ATA
depends on RT_USING_SCSI
default y
help
Build the generic AHCI driver that maps HBA registers (ports, command list,
FIS receive, etc.), handles NCQ, and bridges each detected SATA device to
the RT-SCSI mid-layer so filesystems can treat them like disks. Enable it
whenever your SoC implements a standards-compliant AHCI core; disable if
you rely on a vendor-specific ATA engine.
config RT_ATA_AHCI_PCI
bool "AHCI support on PCI bus"
depends on RT_ATA_AHCI
depends on RT_USING_PCI
default n
help
Allow the AHCI driver to bind to PCI devices and fetch resources via PCI
config space. Required on PC-class hardware where the AHCI HBA is behind
PCI/PCIe; boards with platform AHCI (non-PCI) can leave this off to save a
little code.
