sparc: remove several unnecessary module.h include instances

2011-10-31T23:30:54+00:00

Building an allyesconfig doesn't reveal a hidden need
for any of these.  Since module.h brings in the whole kitchen
sink, it just needlessly adds 30k+ lines to the cpp burden.

sparc: Add CONFIG_DMA_API_DEBUG support

2009-08-10T07:35:00+00:00

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.

sparc: Use asm-generic/pci-dma-compat

2009-08-10T07:35:00+00:00

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.

sparc: Replace sbus_map_single and sbus_unmap_single with sbus_map_page and sbus_unmap_page

2009-08-10T07:35:00+00:00

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).

sparc: remove dma-mapping_{32|64}.h

2009-06-16T11:56:47+00:00

This modifies SPARC32 to use struct dma_map ops. It means that we can
remove dma-mapping_{32|64}.h.

sparc32: Implement more generic dma_*() interfaces.

2008-08-29T09:13:14+00:00

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.
