From 12d04eef927bf61328af2c7cbe756c96f98ac3bf Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Sat, 11 Nov 2006 17:25:02 +1100 Subject: [POWERPC] Refactor 64 bits DMA operations This patch completely refactors DMA operations for 64 bits powerpc. 32 bits is untouched for now. We use the new dev_archdata structure to add the dma operations pointer and associated data to struct device. While at it, we also add the OF node pointer and numa node. In the future, we might want to look into merging that with pci_dn as well. The old vio, pci-iommu and pci-direct DMA ops are gone. They are now replaced by a set of generic iommu and direct DMA ops (non PCI specific) that can be used by bus types. The toplevel implementation is now inline.
