* ArmVirtPkg/FdtPciHostBridgeLib: Add extra pci root buses supportJiahui Cen via groups.io2021-01-201-18/+4
| | | | | | | | | | | | | | | | | | | | | In order to take advantages of extra pci root buses in ArmVirtPkg, it is necessary to scan extra root buses when getting root briges. And now PciHostBridgeUtilityLib already provides a set of utility functions that support for extra pci root buses, like PciHostBridgeUtilityGetRootBridges() / PciHostBridgeUtilityFreeRootBridges(). So let's rebase ArmVirtPkg/FdtPciHostBridgeLib to PciHostBridgeUtilityGetRootBridges() / PciHostBridgeUtilityFreeRootBridges() to extend ArmVirtPkg with extra pci root buses support.

* ArmVirtPkg/FdtPciHostBridgeLib: map ECAM and I/O spaces in GCD memory mapArd Biesheuvel2018-11-292-1/+46
| | | | | | | | | | | | | | | | | | | | Up until now, we have been getting away with not declaring the ECAM and translated I/O spaces at all in the GCD memory map, simply because we map the entire address space with device attributes in the early PEI code, and so the ECAM space will be mapped wherever it ends up. Now that we are about to make changes to how ArmVirtQemu reasons about the size of the address space, it would be better to get rid of this mapping of the entire address space, since it can get arbitrarily large without real benefit. So start by mapping the ECAM and translated I/O spaces explicitly, instead of relying on the early PEI mapping.

| | | | | | | | | | | | If the pci-host-ecam-generic DT node describes a 64-bit MMIO region, account for it in the PCI_ROOT_BRIDGE description that we return to the generic PciHostBridgeDxe implementation, which will be able to allocate BARs from it without any further changes.

* ArmVirtPkg: implement FdtPciHostBridgeLibArd Biesheuvel2016-09-022-0/+456
Implement PciHostBridgeLib for DT platforms that expose a PCI root bridge via a pci-host-ecam-generic DT node. The DT parsing logic is copied from the PciHostBridgeDxe implementation in ArmVirtPkg, with the one notable difference that we don't set some of the legacy PCI attributes for IDE and VGA I/O ranges.
