- 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:

This device shouldn't be considered as an alternative to a Memory Mapped or built-in Ethernet MAC. Throughput is slow (~460kByte/s) while generating a very high system load (~60%). Signed-off-by:

Fix a few problems I discovered when building a kernel with upstream CVS binutils. We have to add the NOTES macro to our linker script, since a kernel built with --build-id is otherwise unable to boot. Last time NOTES was added, it broke things, but the definition of the macro has changed not to rely on parts of the linker script that aren't present on Blackfin. I also noticed that _l2_lma_start does not point into the kernel image, but rather somewhere in L1/L2 space, which seems unintended. Also, when the L2 section was added to the linker script, the part following it which computes then length of the init section was not updated. Signed-off-by:

Remove all traces of the relocation stack. It's been removed from binutils for years now. Add a sanity overflow check to pcrel24 relocations to catch modules that were built without -mlong-calls. Signed-off-by:
