how to add DMA support?

[Rozhuk Ivan]

Hi!

STR813X/CNS213X have:
 - eight-channel Generic DMA controller (GDMA)
 - single-channel High Speed DMA controller (HSDMA)

Both for: memory-to-memory, memory-to-peripheral, peripheral-to-memory, and
peripheral-to-peripheral data transferring with a shared buffer.

Both have IRQ:
- Generic DMA Terminal Counter, Generic DMA Error (GDMA)
- HSDMA Terminal Counter and Error Interrupt.


How I can tell system to use DMA?
How tell to use DMA in ECHI and OCHI standard USB drives?
