>From the device controllers perspective, current drive implementation needs >the below information: * AHCI: HC MMIO BAR & DevicePath * NVMe: HC MMIO BAR & DevicePath * UFS: HC MMIO BAR * SD/MMC: HC MMIO BAR * USB - XHCI: HC MMIO BAR & USB controller type (I think this can be identified by consuming the HC PCI configuration space) * USB - EHCI: Same as XHCI * USB - UHCI: Same as XHCI
I think the interface defined in EDKII_PCI_DEVICE_PPI is sufficient for above needs.
