2009-01-07Blackfin arch: panic when running on a chip rev below what we are compiled forRobin Getz
If we are running on a chip revision below what we are compiled for, there will be missing anomaly workarounds, and a panic is inevitable. Do is sooner, rather than later, so people don't look for bugs that already have workarounds (that they turned off).

2009-01-07Blackfin arch: rewrite dma_memcpy() and dma in/out functionsMike Frysinger
- 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 Signed-off-by: Mike Frysinger <vapier.adi@gmail.com> Signed-off-by: Bryan Wu <cooloney@kernel.org>
