Blackfin: dma: constify MMR pointer array2011-01-10T12:18:05+00:00Mike Frysingervapier@gentoo.org2010-10-25T18:11:09+00:00urn:sha1:5e3bcf30d655c2e277c77b523347685d06bb9d31
The array of pointers is never written, so constify it.

Blackfin: fix DMA/cache bug when resuming from suspend to RAM2010-08-06T16:55:50+00:00Michael Hennerichmichael.hennerich@analog.com2010-06-16T09:12:10+00:00urn:sha1:d1401e1dc22606a91f577ad3dfd68ae7e60e0357
The dma_memcpy() function takes care of flushing different caches for us.
Normally this is what we want, but when resuming from mem, we don't yet
have caches enabled. If these functions happen to be placed into L1 mem
(which is what we're trying to relocate), then things aren't going to
work. So define a non-cache dma_memcpy() variant to utilize in situations
like this.

Some IRQ handlers need to disable a DMA channel without waiting.

Every Blackfin variant has the same DMA bit masks, so avoid duplicating
them over and over in each mach header.
