PATCH 1/1 Add QPACE as a separated Cell platform
From: Benjamin Krill <[email protected]>
Since the QPACE (Chromodynamics Parallel Computing on the Cell Broadband Engine) platform doesn't use a iommu, doesn't have PCI devices and a MPIC much lesser setup and configurations are needed. So far all devices are detected as OF device. A notifier function is used to set the dma_ops for the of_platform bus. Further this patch splits the PPC_CELL_NATIVE into PPC_CELL_COMMON which are parts that are shared with the QPACE platform and the rest.
