Mike Frysinger dd3dd384df Blackfin arch: rewrite dma_memcpy() and dma in/out functions 
- unify all dma in/out functions (takes ~35 lines of code now)
- unify dma_memcpy with dma in/out functions (1 place that touches MDMA0
  registers)
- add support for 32bit transfers
- cleanup dma_memcpy code to be much more readable
- irqs are disabled only while programming MDMA registers rather than
  the entire transaction

Michael Hennerich a2ba8b1998 Blackfin arch: lookup channel2irq() only once 
Add irq to struct dma_channel lookup channel2irq() only once,
since channel2irq() is fairly large on some Blackfin derivatives.
