I want to to transfer data from pl to ddr via DMA(PL330). There is almost no pl330 material,no good example how to use the pl330 linux driver pll330.c . so i don't where i can start with.
Have anybody used pl330? any example or datasheet will be great help,thanks.

Some threads on the linux driver side of things for recent kernel versions:
The PL330 signalling is reasonably documented in the Zynq TRM. I think that info is derived from the PL330 doc at ARM itself.
