Hi,
This patchset is a cleanup of the i8257/i82374 ISA DMA controllers.
Global DMA_* functions will be obsoleted and then deleted, and ISA devices will
not
be tied anymore to i8257 DMA device implementation.
This paves the way to fix support for floppy DMA operations on
sparc/sparc64/MIPS Magnum
platforms (which don't use i8257 DMA controller), and to support multiple ISA
buses on
the same machine.
Patch 1 cleans up the i82374 DMA controller, by removing device inheritance.
Patches 2 to 7 change i8257 to current standards (structures and functions
renaming, QOM)
Patches 8 to 16 create and use a IsaDma interface, to separate devices from
i8257
device implementation.
Patch 17 removes now unused DMA_* functions.
Hervé
Hervé Poussineau (17):
i82374: device only existed as ISA device, so simplify device
i8257: pass ISA bus to DMA_init() function
i8257: rename struct dma_cont to I8257State
i8257: rename functions to start with i8257_ prefix
i8257: make the DMA running method per controller
i8257: add missing const
i8257: QOM'ify
isa: add an ISA DMA interface, and store it within the ISA bus
i8257: implement the IsaDma interface
magnum: disable floppy DMA for now
sparc: disable floppy DMA
sparc64: disable floppy DMA
fdc: use IsaDma interface instead of global DMA_* functions
cs4231a: use IsaDma interface instead of global DMA_* functions
gus: use IsaDma interface instead of global DMA_* functions
sb16: use IsaDma interface instead of global DMA_* functions
dma: remove now useless DMA_* functions
