| * [ARM] dma: RiscPC: don't modify DMA SG entriesRussell King2009-02-211-5/+9
| | | | | | | | | | | | | | | | | | We should not be modifying the scatterlist passed to us from the driver code; doing so breaks assumptions made by the DMA API code, and could cause problems if the driver retries a transfer using an old scatterlist.

| * [ARM] dma: Use sensible DMA parameters for Acorn driversRussell King2008-12-111-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | The hardware supports transfers up to a page boundary per buffer. Currently, we work around that in the DMA code by splitting each buffer up as we run through the scatterlist. Avoid this by telling the block layers about the hardware restriction. Eventually, this will allow us to phase out the splitting code, but not until the old IDE layer allows us to control the value it gives to blk_queue_segment_boundary().

| * [ARM] dma: move RiscPC specific DMA data out of dma_structRussell King2008-12-112-73/+91
| | | | | | | | | | | | | | Separate the RiscPC specific (IOMD and floppy FIQ) data out of the core DMA structure by making the IOMD and floppy DMA supersets. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
| * [ARM] dma: rejig DMA initializationRussell King2008-12-116-47/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than having the central DMA multiplexer call the architecture specific DMA initialization function, have each architecture DMA initialization function use core_initcall(), and register each DMA channel separately with the multiplexer. This removes the array of dma structures in the central multiplexer, replacing it with an array of pointers instead; this is more flexible since it allows the drivers to wrap the DMA structure (eventually allowing us to transition non-ISA DMA drivers away.)

Although EM-X270 is similar to CM-X2XX, it has a lot of unique features. Keeping these features in the same _defconfig increases the kernel size in the way it does not fit into CM-X2XX NOR flash.
