*	sh: fix DMA driver's descriptor chaining and cookie assignment	Guennadi Liakhovetski	2009-12-17	1	-3/+6
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	The SH DMA driver wrongly assigns negative cookies to transfer descriptors, also, its chaining of partial descriptors is broken. The latter problem is usually invisible, because maximum transfer size per chunk is 16M, but if you artificially set this limit lower, the driver fails. Since cookies are also used in chunk management, both these problems are fixed in one patch. As side effects a possible memory leak, when descriptors are prepared, but not submitted, and multiple races have also been fixed.

*	dmaengine: sh: Add Support SuperH DMA Engine driver	Nobuhiro Iwamatsu	2009-09-08	1	-0/+64
	This supported all DMA channels, and it was tested in SH7722, SH7780, SH7785 and SH7763. This can not use with SH DMA API.
