2009-08-10sparc: Add CONFIG_DMA_API_DEBUG supportFUJITA Tomonori1-32/+5
All we need to do for CONFIG_DMA_API_DEBUG support is call dma_debug_init() in DMA code common for SPARC32 and SPARC64. Now SPARC32 uses two dma_map_ops structures for pci and sbus so there is not much dma stuff for SPARC32 in kernel/dma.c. kernel/ioport.c also includes dma stuff for SPARC32. So let's put all the dma stuff for SPARC32 in kernel/ioport.c and make kernel/dma.c common for SPARC32 and SPARC64.

2009-08-10sparc: Use asm-generic/pci-dma-compatFUJITA Tomonori1-148/+7
This converts SPARC to use asm-generic/pci-dma-compat instead of the homegrown mechnism. SPARC32 has two dma_map_ops structures for pci and sbus (removing arch/sparc/kernel/dma.c, PCI and SBUS DMA accessor). The global 'dma_ops' is set to sbus_dma_ops and get_dma_ops() returns pci32_dma_ops for pci devices so we can use the appropriate dma mapping operations.

2009-08-10sparc: Replace sbus_map_single and sbus_unmap_single with sbus_map_page and ↵FUJITA Tomonori1-3/+2
sbus_unmap_page This is a preparation for using asm-generic/pci-dma-compat.h; SPARC32 has two dma_map_ops structures for pci and sbus (removing arch/sparc/kernel/dma.c, PCI and SBUS DMA accessor).

2009-06-16sparc: remove dma-mapping_{32|64}.hFUJITA Tomonori1-59/+40
This modifies SPARC32 to use struct dma_map ops. It means that we can remove dma-mapping_{32|64}.h. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Tested-by: Robert Reif <reif@earthlink.net> Signed-off-by: David S. Miller <davem@davemloft.net>

These dispatch to either PCI or SBUS routines based upon the device bus type. This will allow us to let SBUS drivers call these routines. Signed-off-by: David S. Miller <davem@davemloft.net>
