1PciEmulation configuration 2-------------------------- 3Installation of various NonDiscoverable devices via PciEmulation driver is performed 4via set of PCDs. Following are available: 5 6 gMarvellTokenSpaceGuid.PcdPciEXhci 7 8Indicates, which Xhci devices are used. 9 10 gMarvellTokenSpaceGuid.PcdPciEAhci 11 12Indicates, which Ahci devices are used. 13 14 gMarvellTokenSpaceGuid.PcdPciESdhci 15 16Indicates, which Sdhci devices are used. 17 18All above PCD's correspond to hardware description in a dedicated structure: 19 20STATIC PCI_E_PLATFORM_DESC A70x0PlatDescTemplate 21 22in Platforms/Marvell/PciEmulation/PciEmulation.c file. It comprises device 23count, base addresses, register region size and DMA-coherency type. 24 25Examples 26-------- 27Assuming we want to enable second XHCI port and one SDHCI port on Armada 2870x0 board, following needs to be declared: 29 30 gMarvellTokenSpaceGuid.PcdPciEXhci|{ 0x0 0x1 } 31 gMarvellTokenSpaceGuid.PcdPciESdhci|{ 0x1 } 32
