Hello!

If what you want is to do dma without having to use any frameworks, you have to export the kernel mode dma functionality into userspace:

Create a character device driver which accepts ioctls from usermode, thus exposing the functionality present in "asm/arch-davinci/edma.h"

I hope i could help.
