DMA to static address

Hi,

I've been looking around in the kernel source and googling, and I'm
having trouble finding any information about doing a DMA transfer with
an I/O device that implements a single address for DMA.  I.e. the
external memory address should not be auto incremented during the
transfer.

Is that mode supported by the Linux generic DMA system, and where should
I look?

Specifically this is for the i.MX27 and friends.

Regards,
James.
