DMA in pxa27x processor kit

Hi

Iam trying to implement DMA mode of transfer in a kit with PXA27x
processor interfaced with HOST FPGA.
In the standard Wince5.0 driver code provided I used the virtual alloc
function to
map the DMA controller registers - DCMDX.
Can DMA controller registers can be mapped virtually or some other API
should be used?
please reply.

Thanks,
Meribha

Yes they can and should be mapped. Do you have a problem?
