2008-08-04powerpc: Move include files to arch/powerpc/include/asmStephen Rothwell
from include/asm-powerpc. This is the result of a mkdir arch/powerpc/include/asm git mv include/asm-powerpc/* arch/powerpc/include/asm Followed by a few documentation/comment fixups and a couple of places where <asm-powepc/...> was being used explicitly. Of the latter only one was outside the arch code and it is a driver only built for powerpc. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-12-04[POWERPC] Refactor 64 bits DMA operationsBenjamin Herrenschmidt
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.

2006-12-01Driver core: add dev_archdata to struct deviceBenjamin Herrenschmidt
Add arch specific dev_archdata to struct device Adds an arch specific struct dev_arch to struct device. This enables architecture to add specific fields to every device in the system, like DMA operation pointers, NUMA node ID, firmware specific data, etc...
