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. if RT_USING_ATA osource "$(SOC_DM_ATA_DIR)/Kconfig" endif
