Ard Biesheuvel 62a75650e4 EmbeddedPkg/NonCoherentDmaLib: implement support for DMA range limits
Implement support for driving peripherals with limited DMA ranges to
NonCoherentDmaLib, by adding a device address limit, and taking it,
along with the device offset, into account when allocating or mapping
DMA buffers.
