Now that Laszlo's virtio-gpu-pci have removed the last remaining obstacle,
we can get rid of the special PciHostBridgeDxe implementation in ArmVirtPkg,
and move to the generic one. This will allow us to perform DMA above 4GB
without bounce buffering, and use 64-bit MMIO BARs.
Patch #1 removes the linux,pci-probe-only override which does more harm than
good now that we switched to virtio-gp-pci, which does not expose a raw
framebuffer.
Patch #2 implements PciHostBridgeLib for platforms exposing a PCI host bridge
using a pci-host-ecam-generic DT node.
Patch #3 switches to the generic PciHostBridgeDxe, with no change in
functionality other than support for DMA above 4 GB without bounce buffering.
Patch #4 adds support for 64-bit MMIO BARs
Patch #5 removes the now obsolete PciHostBridgeDxe from ArmVirPkg.
Ard Biesheuvel (5):
ArmVirtPkg/PciHostBridgeDxe: don't set linux,pci-probe-only DT
property
ArmVirtPkg: implement FdtPciHostBridgeLib
ArmVirtPkg/ArmVirtQemu: switch to generic PciHostBridgeDxe
ArmVirtPkg/FdtPciHostBridgeLib: add MMIO64 support
ArmVirtPkg: remove now unused PciHostBridgeDxe
