Russell Currey 8e3f1b1d82 powerpc/powernv/pci: Enable 64-bit devices to access >4GB DMA space ... On PHB3/POWER8 systems, devices can select between two different sections of address space, TVE#0 and TVE#1. TVE#0 is intended for 32bit devices that aren't capable of addressing more than 4GB. Selecting TVE#1 instead, with the capability of addressing over 4GB, is performed by setting bit 59 of a PCI address. However, some devices aren't capable of addressing at least 59 bits, but still want more than 4GB of DMA space. In order to enable this, reconfigure TVE#0 to be suitable for 64-bit devices by allocating memory past the initial 4GB that is inaccessible by 64-bit DMAs. This bypass mode is only enabled if a device requests 4GB or more of DMA address space, if the system has PHB3 (POWER8 systems), and if the device does not share a PE with any devices from different vendors.
