Asha,
You let the kernel now that X amount is DMA space only. It depends on
architecture though. What is architecture being worked upon?

Opps, sorry.
It should be "memmap=256M$0x1000"

Hi,
I want to reserve one range of physical memory say from 0x1000 of 256MB
in Linux. This region is required for DMA functions alone.
Please help me understand how we can reserve this in Linux. Can this be
done using boot options or any other?

Asha
