2016-09-05 Thread Ard Biesheuvel
After moving ArmVirtQemu to the generic PciHostBridgeDxe, we noticed that setting DmaAbove4G resulted in problems with the emulated EHCI USB host controller, which were caused by the fact that the PCI layer was providing DMA buffers allocated above 4 GB while the emulated EHCI controller in QEMU
