      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.

    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.
